Sum of measure of interior angles of polygon
Web19 Feb 2024 · The formula for the sum of the interior angles of a regular polygon is (n - 2) * 180, where n is the number of sides. Therefore, 1620 = (n - 2) * 180 Solving for n, we get: 1620 = (n - 2) * 180 1620/180 = (n - 2) 9 = n - 2 n = 11 Therefore, the polygon has 11 sides. answered February 19, 2024 Answer this Question Still need help?
