Try making a general formula for the sides of a regular polygon from pictures. A useful hint would be, remember that you can make any regular polygon into a bunch of equal triangles and the center contains a full 360 degrees and all triangles have 180 degrees.

it can be the number of factors 360 will have and its 22 (leaving 0 and 360)

see each int angle of regular poly gon is given by 180 (360/n)

You can forget a formula, but if you can figure it out like this, you can do it on the test.

\(\dfrac{180(n  2)}{n}\) is the measure of an angle in a regular polygon. So, you can always test the choices ;)
