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 22 Gon?

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˚. Each angle of a regular polygon measures 157.5˚.

9

How many sides does a polygon have if the sum of the measures of the interior angles is 1980º?

where n is the number of sides of the polygon. Hence, the polygon has 13 sides .

What is the sum of the interior angles of a pentagon?

540°

What is the sum of interior angles of a 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.

What is the sum of the interior angles of a polygon shown below?

To find the sum of the interior angles, multiply the number of triangles by 180. B) The sum of the interior angles in a polygon is always 360 degrees .

How do you find the sum of the interior angles of a 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.

What does sum of interior angles mean?

Sum of Interior Angles Formula This formula allows you to mathematically divide any polygon into its minimum number of triangles. Since every triangle has interior angles measuring 180° , multiplying the number of dividing triangles times 180° gives you the sum of the interior angles .

What is the interior angle of a 12 sided polygon?

150°

What do you call the sum of the sides of a polygon?

“Tri” means “three,” so the simplest polygon is called the triangle, because it has three angles . In this formula, the letter n stands for the number of sides , or angles , that the polygon has. sum of angles = (n – 2)180° Let’s use the formula to find the sum of the interior angles of a triangle.
