Question

find the sum of the interior angle measures of the polygon. the sum of the interior measures of the polygon is (square^{circ}).

Explanation:

Step1: Identify the number of sides

The polygon is a nonagon (9 - sided polygon), so \(n = 9\).

Step2: Use the formula for the sum of interior angles

The formula for the sum of interior angles of a polygon is \(S=(n - 2)\times180^{\circ}\).
Substitute \(n = 9\) into the formula:
