OpenStudy (misssunshinexxoxo):
Sum of interior angles = 180(n-2). n being the number of angles the polygon has. You would then divide it by the number of sides. The sum of the exterior angles of a polygon always equals 360 degrees, so then just divide this by the number of exterior angles and you will get the measure of one of them

So just 180(n-2) as the main formula then?
