How many sides does a regular polygon have if each exterior angle measures 12?

OpenStudy (nurali):

The formula for finding the measure of the exterior angle of a regular polygon is 360/n, where n is the number of sides. (Also the sum of any polygon's exterior angles is 360 degrees.) So: 360/n = 12 360 = 12n n = 30
