Star Study - Integral Angles

Geometry Level 3

Take nn points that are equally spaced on the circumference of a circle. For each point, connect it to the 2 points that are furtherest away from it, but not diametrically opposite to it. This forms an nn pointed star.

For how many integers n5n \geq 5 is the measure (in degrees) of an individual internal angle in an nn pointed star also an integer?
