Question

What is the measure of an interior angle of a regular polygon of 9 sides

Answer 1

Given number of interior angles n = 9.

We know that measure of one interior angle = (n - 2) * 180/n

= (9 - 2) * 180/9

= (7)(180)/9

= 140 degrees.

Therefore, measure of each interior angle = 140 degrees.

Hope this helps!
