The following picture is to help give an idea on what a congruent answer is. Each matching color on the following graph are what congruent angles look like.
So we’re going to use the same approach for your equation. You need to find what angle is congruent with <7... so your answer is going to be <1. I hope this helps.

So you want to solve for x?
It would be nice if this would easily factor:
(-4x + 5)(2x +1) = 0 This will not work!
So you need to use the quadratic formula:
a = -8, b = 4, c = 5
x = (-4 +/-
)/2(-8)
= (-4 +/-
)/-16
= (-4 +
)/-16
= 1/4 -
/4

Answer:
≈119.3
Step-by-step explanation:
The area for circumference is as follows:
The above equations mean the same thing, because the diameter is just 2 times the radius.
Anyhow, we insert this value into the equation...
This rounds to:
≈119.3
