Find the sum of the interior angle measures of the polygon.

The sum of the interior angle measures of the polygon is 900 degrees

The formula for finding the sum of an interior angle of a polygon is expressed according to the formula:

n is the number of sides of the polygon

The given polygon has 7 sides (heptagon)

S = (7 - 2) * 180

S = 5 * 180

s = 900 degrees

Hence the sum of the interior angle measures of the polygon is 900 degrees

The formula for finding the sum of the measure of the interior angles is (n - 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n - 2) * 180 / n.
