The formula in finding the sum or the total measure of the interior angles of polygon having n sides is:
Sum of interior angles = (n – 2) 180
Where n = number of sides of the polygon
In this problem, you are asked for the sum of the interior angles of a 17 sided polygon. You have to substitute the number of sides to the formula:
Sum of interior angles = (17 – 2) 180
Sum of interior angles = (15) 180
Sum of interior angles = 2,700 degrees
