once you know the sum of the interior angles in a polygon it is easy to find the measure of one interior angle if the polygon is regular: all sides are congruent and all angles are congruent. just divide the sum of the angles by the number of sides.
the interior angle of a polygon is one of the angles on the inside.
answer: 22 1/2
step-by-step explanation: first convert 4 1/2 into a mixed # = 9/2
the divide that by 5 (mult by reciprocal)
reciprocal is the # flipped so,
9/2 x 1/5
divide 45 by 2
