Question

Find the measure of an angle

in a regular polygon with 28
sides.
[?] degrees
Round to the nearest whole number.

Answer 1

167º

Explanation:

The interior angles in an n-gon add up to 180(n-2). So, the interior angles in a 28-gon add up to 180(28-2)=180(26)=4680. To find out the measure of one angle divide 4680 by 29. 4680/28 is about 167.
