Answer:
12
Step-by-step explanation:
The Pythagorean theorem shows that 400 or 20² - 256 or 16² = 144 or 12² which means that the other side is 12
x=12
measure of central angle is 4.607 radians with an arc length equaling 29.21 and a circumference = 40.44
Step-by-step explanation:
Arc length = 29.21
Circumference = 40.44
Central angle = ?
The formula used to find central angle is:

where s = arc length, r= radius and Ф=central angle.
We need to find radius from circumference

So, radius = 6.34
Now, finding central angle:

So, measure of central angle is 4.607 radians with an arc length equaling 29.21 and a circumference = 40.44
