for each of the following determine the measure of an interior angle and the measure of an exterior angle. A regular dodecagon and an equiangular pentagon. *HELP*

Ahh I remember this. 12 sides. The formula is (n-2)*180, n represting the number of sides. 12-2=10, 10*180=1800, then divide by n, and get 150. :)
