Question

What is the measure of an exterior angle of a 25-gon?

Answer 1

I assume that it is a regular polygon. The sum of the measures of the exterior angles of a polygon is always 360 degrees. 360/25=14.4 degrees Each interior angle is... (n-2)(180)=(25-2)(180)=23*180=4140 degrees 4140/25=165.6 degrees for each interior angle each interior angle and it's exterior angle are supplementary 165.6+14.4=180 degrees
