#### A polygon has 11 sides. What is the sum of the measure of the interior angles of the polygon?

## 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).

## How many sides does a polygon have if the sum of the interior angles is 1260?

9

## What is the sum of the interior angles for a 40 sided polygon?

In geometry, a tetracontagon or tessaracontagon is a forty-sided polygon or 40-gon. The sum of any tetracontagon’s interior angles is 6840 degrees .

## How do you find the number of sides in a polygon given the interior angle?

Subtract the interior angle from 180. For example, if the interior angle was 165, subtracting it from 180 would yield 15. Divide 360 by the difference of the angle and 180 degrees. For the example, 360 divided by 15 equals 24, which is the number of sides of the polygon .

## 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 the interior angles?

Properties. The sum of the internal angle and the external angle on the same vertex is 180°. The sum of all the internal angles of a simple polygon is 180(n–2)° where n is the number of sides.

## How many sides does a polygon have if the sum of the interior angles is 1620?

So, the sum of the interior angles of an 11-gon is 1620 degrees. All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles , we know that the sum of all the angles is 1620 degrees (from above) And there are eleven angles

## How many sides does a polygon have if the sum of the interior angles is 1440?

The sum of the measures of the interior angles of a decagon (10 sided polygon ) is 1,440 . We found this by using the formula (n-2)(180).

## How many sides does a polygon have if the sum of the interior angles is 2700?

17 sides

## What is the interior angle sum of a polygon with 10 sides?

A decagon is a 10 – sided polygon, with 10 interior angles , and 10 vertices which is where the sides meet. A regular decagon has 10 equal-length sides and equal-measure interior angles . Each angle measures 144° and they all add up to 1,440° .

## 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.

## What is the sum of interior angles of a Heptagon?

900°

## How many sides does a polygon have with an interior angle of 720?

6 sides

## How many sides does a regular polygon have if the measure of each interior angle is 60?

Answer and Explanation: There are three sides in this regular polygon .

## How many sides does a polygon have with an interior angle of 135?
