Question

find the measure of an interior angle and an exterior angle of a regular pentagon

Answer 1

Answer:

interior is 108 degrees and exterior is 72 degrees

Step-by-step explanation:

The total sum of angles in a polygon is (n-2)*180 degrees, where n is the number of sides....here n is 5 so total angle is 540 degrees.....no there are 5 angles and in regular polygon all angles are equal so interior angle is 540/5=108 degrees.......by using linear pair concept , exterior and interior angles are supplementary, so exterior angle =180-interior,

so exterior= 72 degrees
