I'm Using my last points will give brainliest geometry - finding angles with justification (level 1) delta math Please do step by step and pick reasoning for each
here are reasonings to pick from:
verticle angles
Linear pair (or triples)
Congruent angles
sum of angles in a triangle
sum of angles in a quadrilateral
Base angles of an isosceles triangle
Angle bisector definition
corresponding angles
alternate interior angles
alternate exterior angles
same - side interior angles
angle addition postulate
angle subtraction postulate
perpendicular lines form right angles
Answer:
m<GFC = 69 degrees
Step-by-step explanation:
The angle with 37 degrees is congruent with the angle on the left of 74 because of the Alternate Interior Angles Postulate
The last angle in the triangle that you don't know the degrees of is on the right of angle 74 because of the Alternate Interior Angles Postulate
So 37+74+ (the degree we don't know of the triangle) = 180 because of linear triples
180 - (37+74) = 69
So the angle on the right of angle 74 = 69
So m<GFC = 69 degrees
Answer:
Its 69
Step-by-step explanation:
the three measures will add up to 180 so all you hace to do is add the angles given and subtract that from 180 to find x
find the coordinates of the point equidistant from (4,-6) and the origin, as well as on the line 2x-y=9
We have to find the coordinates of the point equidistant from (4,-6) and the origin, as well as on the line 2x-y=9.
We can graph the line and the points to have an idea of the problem:
We can write the distance from our point (x,y) to the point (4,-6) as:
\(D_1=\sqrt[]{(x-4)^2+(y+6)^2}\)If we replace y with the value of the equation we get:
\(2x-y=9\longrightarrow y=2x-9\)\(D_1=\sqrt[]{(x-4)^2+(2x-9+6)^2}=\sqrt[]{(x-4)^2+(2x-3)^2}\)For the distance of our point (x,y) to the origin (0,0) we get:
\(\begin{gathered} D_2=\sqrt[]{(x-0)^2+(y-0)^2} \\ D_2=\sqrt[]{x^2+(2x-9)^2} \end{gathered}\)If the point is equidistant to both points, both distances are equal, so we can write:
\(\begin{gathered} D_1=D_2 \\ \sqrt[]{(x-4)^2+(2x-3)^2}=\sqrt[]{x^2+(2x-9)^2} \\ (x-4)^2+(2x-3)^2=x^2+(2x-9)^2 \\ (x^2-8x+16)+(4x^2-12x+9)^2=x^2+(4x^2-36x+81) \\ 5x^2-20x+25=5x^2-36x+81 \\ 5x^2-5x^2-20x+36x=81-25 \\ 16x=56 \\ x=\frac{56}{16} \\ x=3.5 \end{gathered}\)We know the x-coordinate (x=3.5), so we can now calculate the y-coordinate as:
\(y=2x-9=2\cdot3.5-9=7-9=-2\)Then, the coordinates for the equidistant point is (3.5, -2)
We can graph this as:
Answer: Coordinates of the point (x,y)=(3.5,-2)
Ellie, Mrs. Trost's youngest daughter, gained 0.6 pounds in 0.25 months.
What was Ellie's growth rate in pounds (lb) per month?
Ellie's growth rate is 2.4 pounds per month.
To find Ellie's growth rate in pounds per month, we divide the change in weight by the time period. Let's calculate it using the given information:
Determine the change in weight:
Change in weight = 0.6 pounds
Determine the time period:
Time period = 0.25 months
Calculate the growth rate:
Growth rate = Change in weight / Time period
Substituting the values:
Growth rate = 0.6 pounds / 0.25 months
To divide by a fraction, we multiply by its reciprocal:
Growth rate = 0.6 pounds * (1 / 0.25 months)
Simplifying the fraction:
Growth rate = 0.6 pounds * 4 months
Multiplying:
Growth rate = 2.4 pounds per month
Therefore, Ellie's growth rate is 2.4 pounds per month. This means that, on average, she gains 2.4 pounds every month.

Tan(x/2) = (1 + cosx)/sinx is equivalent to the trigonometric identity cscx
How to solve an equation?An equation is an expression that can be used to show the relationship between variables and numbers.
Trigonometric identities are based on the six trigonometric ratios. They are sine, cosine, tangent, cosecant, secant, and cotangent.
It is given as:
tanФ = sinФ/cosФ, cotФ = 1/tanФ = cosФ/sinФ, cosecФ = 1/sinФ and secФ = 1/cosФ
According to half angle formula:
tan(x/2) = (1 + cosx)/sinx
Hence:
tan(x/2) + cotx = [(1 - cosx)/sinx] + (cosx/sinx)
tan(x/2) + cotx = (1 - cosx + cosx)/sinx
= 1/sinx
= cscx
Therefore tan(x/2) = (1 + cosx)/sinx is equivalent to cscx

We need to find how many square inches of plastic does the company need to make 10 beach balls.
Let A be the area of 1 ball. Balls are in the form of spheres. The area of a sphere is given by :
\(A=4\pi r^2\)
For 10 balls,
\(A=10\times 4\pi r^2\\\\=10\times 4 \times 3.14\times (2)^2\\\\=502.4\ \text{inches}^2\)
Hence, the area of 10 beach balls is \(502.4\ \text{inches}^2\).

Answer:
f(x) = - 2x + 4
Step-by-step explanation:
Since we are only trying to move the graph up 3 units, the slope does not change. So, it would be -2.
We also know that the 1 in f(x)= -2x + 1 is the y-intercept (y=mx+b). But again, we are moving the graph 3 units up, so we have to add 3. That makes it 4 (3+1=4).
So, the new equation would be f(x) = -2x + 4
Step-by-step explanation:
it simply means that g(x) is f(x) just shifted 3 units upwards.
that means nothing else changes, only whatever y result f(x) produces is increased by 3.
so,
g(x) = f(x) + 3 = -2x + 1 + 3 = -2x + 4
therefore, as domain and range were the whole set of real numbers, the addition of 3 does not make any difference in relation to infinity. so, they remain unchanged.
the slope stays the same (g(x) is simply a parallel line to f(x)).
the y-intercept (the y-value when x = 0) also increases by 3, and is 4.
the x-intercept (the x-value when y = 0) changes :
0 = -2x + 4
2x = 4
x = 2
the x-intercept is 2.

The formula for the volume of a pyramid is uppercase V = one-third uppercase B h Which of the following equations is equivalent to the given formula?
Step-by-step explanation:
One possible equivalent equation to the given formula is:
uppercase B = 3 uppercase V ÷ h
To see why this equation is equivalent, we can isolate uppercase B in the original formula by multiplying both sides by 3/h:
3/h * uppercase V = 3/h * (one-third uppercase B h)
Simplifying the right-hand side:
3/h * (one-third uppercase B h) = uppercase B
Substituting back in the original formula gives:
uppercase B = 3/h * uppercase V

: A major corporation is building a 4325 acre complex of homes, offices, stores, schools, and churches in the rural community of Glen Cove. As a result of this development, the planners have estimated that Glen Clove's population (in thousands) t yr from now will be given by the following function.P(t) = 35t^2 + 125t + 200/t^2 + 4t + 40(a) What is the current population of Glen Cove? (b) What will be the population in the long run?
The current population of Glen Cove is 5,000 people and in the long-run, the population of Glen Cove will approach 35,000 people.
Corporation:A corporation may be a corporate entity whose shareholders elect a board of directors to supervise its operations. the dissimilarity between the business and an organization is that an organization may be a sort of business that's suitable for smaller businesses and organizations, whereas a corporation may be a kind of business that's appropriate for larger enterprises and entities.
The population in Glen Clove's population that is t years from now will be
P(t) = \(\frac{35t^2 + 125t + 200}{t^2 + 4t + 40}\)
The current population can be calculated by substituting t = 0 in P(t).
So,
P(0) = \(\frac{35(0)^2 + 125(0) + 200}{(0)^2 + 4(0) + 40}\)
P(0) = 5
Thus, the current population of Glen Clove is 5 thousand.
(b)For the long run, t tends to infinity. So, evaluate the infinite limit for the given function as follows:
\(\lim_{t \to \infty} P(t)= \lim_{t \to \infty}P(t)\frac{35t^2 + 125t + 200}{t^2 + 4t + 40}\)
=\(\lim_{t \to \infty}\frac{t^2(35+\frac{125}{t} +\frac{200}{t} )}{t^2(1+\frac{4}{t} +\frac{40}{t^2} )}\)
= \(\lim_{t \to \infty}\frac{(35+\frac{125}{t} +\frac{200}{t} )}{1+(\frac{4}{t} +\frac{40}{t^2} )}\)
Now, solve further by putting the limits as follows:
As t approaches infinity, the terms in the numerator approach 0, while the terms in the denominator approach 1, so the limit of P(t) as t approaches infinity is:
lim t -> infinity P(t) = 35 / 1 = 35
So, in the long-run, the population of Glen Cove will approach 35,000 people.

Points A and B are on opposite sides of a lake. Another point, C. is 94.4 meters from Angle A. The measure of Angle A is 72° and the measure of Angle C is 30°. Find the distance between A and B.
To find the distance between points A and B, we can use trigonometry and the given information.
Let's label the distance between A and B as "d". We know that point C is 94.4 meters away from point A. From angle A, we have the measure of 72°, and from angle C, we have the measure of 30°.
Using trigonometry, we can use the tangent function to find the value of "d".
tan(72°) = d / 94.4
To solve for "d", we can rearrange the equation:
d = tan(72°) * 94.4
Using a calculator, we can evaluate the expression:
d ≈ 4.345 * 94.4
d ≈ 408.932
Therefore, the distance between points A and B is approximately 408.932 meters.
