Question

If a decagon is a regular decagon, then what is the measure of each interior angle?

a. 150°
b. 162°
c. 144°
d. 240°

Answer 1

c. 144

Explanation:

In a regular polygon, each interior angle has the same measure. There is a formula to find the angle given the number of sides. We are looking at a decagon, which has ten sides, so we would plug the value 10 into the following formula:

`(180(n-2))/(n)\\(180(10-2))/(10) \\(180*8)/(10) \\18*8\\144`

This is option c.
