Question 392282: What is the number of degrees in the measure of one exterior angle of a regular pentagon?
All I know is the interior angles add up to 540, meaning one interior angle would be 108 degrees. But that isnt exterior.

Hi

The sum of the measures of the exterior angles of a polygon, one at each vertex, is 360°. 

Regular Pentagon: measure of each exterior would be: (180°-108° = 72°)

Note: 5*72° = 360°
