Question 626214: What is the sum of the measures of the interior angles of a regular polygon where a single exterior angle measures 72°? Answer by Emsley(35) (Show Source):
You can put this solution on YOUR website! For any polygon sum of exterior angles =360 So this polygon has 360/72=5 vertices
Each interior angle =180-72=108 So sum of interior angles=5 times 108 =540
