**MathMate**, Tuesday, February 23, 2010 at 8:27pmThe angle at the tip of the star's points is called the point angle, and the angle subtended by two adjacent sides between two points is the dent angle.

In this case, the point angle, p, is 12° and there are 20 points (=n) in the star.

The dent angle can be obtained by:

D=(360/n)+p

=(360/20)+12

= 30 °.
