Then subtract 2 from the total number of sides and multiply by 180. Then, the last step is to divide the answer by the original number of sides.

To find the measure of each exterior angle on a polygon, you need to add up all the numbers and set them equal to 360, because all the exterior angles of a plygon added up eqaul 360. Then, solve for //x//. //X// equals 55. Then, insert 55 in for //x//. The sum or quotient is the measure of that angle. To find an interior angle, we subtract one of the exterior angles from 180, because the two angles form a linear pair.
