Answer:
x=70
Step-by-step explanation:
The value of x is 70 because this triangle is isosceles, meaning that there are two congruent sides and two congruent angles (which are the base angles). x is one of the base angles, 70º is the other base angle's measurement, so x=70.
The formula for a circle's area is
. We are given an area of 38.465 square inches for a quarter of it.
Multiply this value by 4 to compensate for the quarter circle.


Divide both sides by pi (Note: I'm using the conventional value of 3.14)

Take the positive square root of both sides

The radius is 7 inches. Let me know if you have any questions, thanks!
