Question

14 Find the measure of each exterior angle of a regular polygon of 9 sides ,find the measure of its complimentary angle​

Answer 1

Step-by-step explanation:

General formula for finding the size of a regular polygon’s exterior angle is 360/n where n is the number of sides. A walk around the perimeter of the polygon would find the walker take one full turn, 360 degrees, and in a regular polygon this will be broken down in to n turns, one for each side walked down.

So for a 9 sided regular polygon, EA = 360/9 = 40 degrees
