## What is the sum of the interior angle measures of this polygon?

(n-2)x 180 degrees: The formula for finding the sum of all angles in a polygon (REGULAR). Here “n” represents the number of sides of the polygon.

## What is the formula to find the sum of the interior angles of a polygon with n sides?

Theorem 39: If a convex polygon has n sides, then its interior angle sum is given by the following equation: S = ( n −2) × 180°.

## Is there a polygon with an interior angle sum of 9000?

32) Is there a regular polygon with an interior angle sum of 9000 °? Yes, regular 52-gon.

## What is the formula for interior angles?

An interior angle is located within the boundary of a polygon. The sum of all of the interior angles can be found using the formula S = (n – 2)*180. It is also possible to calculate the measure of each angle if the polygon is regular by dividing the sum by the number of sides.

## What is the sum of interior angles of a 15 sided polygon?

Each triangle has an angle sum of 180 degrees, so the sum of the interior angles of the 15-gon must be 13 × 180 = 2340 degrees.

## What is the sum of the measures of the interior angles of a 13 sided polygon?

Question 130236: What is the sum of the measures of the interior anles of a convex 13-gon? There is a formula the sum of the measures of the interior angles of a convex n-gon is (n-2)180 degrees. For a triangle, n=3, so it’s (1)180=180 degrees.
