If it's a regular polygon then each exterior angle measures 36 degrees

A regular polygon will have 360 sides with exterior angles of 181 degrees.

360/number of sides

It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line

360/number of sides = each exterior angle
