What is the sum of the interior angles in a 20 sided polygon if it is a regular polygon What would the measure of each interior angle be?

Each interior angle of a regular polygon of 20 sides = 180 – 18 = 162 deg. Total sum of the 20 interior angles of the regular polygon = 162*20 = 3240 deg.

What is the measure of each interior angle of regular 20 sided polygon?

162°

How do you find the sum of a 20 sided polygon?

The formula for calculating the sum of the interior angles of a polygon is as follows:

  1. (n−2)⋅180.
  2. n is the number of sides of the polygon.
  3. In this case, we can plug in 20 to get the following:
  4. (20−2)⋅180.
  5. 18⋅180.
  6. 3,240.

How much more is the sum of the angles of a 20 sided polygon than a 12 sided polygon?

1,440° Now in the question we are asked to find How much more is the sum of the angle of a 20 sided polygon than a 12 sided polygon. So, We can just subtract the angle sum of 12 sided polygon from 20 sided polygon.

What is the sum of the angles of a 22 sided polygon?

3600˚
Find the sum of the interior angles of a 22-gon. Since the polygon has 22 sides, we can substitute this number for n: (n 2)180˚= (22 2)180˚= 20180˚= 3600˚.

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

2340 degrees
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 interior angles in a regular polygon?

To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°. The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal.

How do you find the sum of a regular polygon?

A regular polygon is a flat shape whose sides are all equal and whose angles are all equal. The formula for finding the sum of the measure of the interior angles is (n – 2) * 180. To find the measure of one interior angle, we take that formula and divide by the number of sides n: (n – 2) * 180 / n.

How do you find the measure of an exterior angle of a regular polygon with 20 sides?

s = 360°. The measure of each exterior angle of a regular 20-gon is 18°.
