If a polygon has n sides, then the sum of its interior angles is:
180+%28n+-+2%29
so, if sum of interior angles is 3240°, than we have
3240+=+180+%28n+-+2%29
n+-+2+=+18
n+=+20 the number of sides
to find the measure of one of the interior angles of the polygon divide the total interior angles by the number of sides (which is also number of angles):
3240%2F20=162°
