Each exterior angle of a regular polygon is 15 degrees.
1.Determine the number of sides of the polygon.


2.What is the sum of the interior angles?

please help!!!!!!!!

i'd love to help but i can't remember how to do those problems. sorry.

The sum of all the exterior angles of a regular polygon is 360ยบ.

So divide 360 by 15 to get the number of sides.

for the interior angles, recall that the sum is 180x(n-2) where n is the number of sides you just found.

Ineed help on my homework
