What is the sum of the interior angles of a polygon with 19 sides?
A enneadecagon is a polygon with 19 sides, and the sum of its interior angles is 3060 degrees.
How many sides would a polygon have if its interior angles are exactly 179 degrees?
360 sides
The sum of the exterior angles of any polygon is 360°. Bonus Question: What is the largest number of sides a shape can have such that its interior angle is an integer? 360 sides. The interior angle will be 179°.
What is the sum of the interior angles of an 18 Gon?
The sum of the measures of the interior angle of any polygon is the number of sides minus 2 multiplied by 180. A polygon with 18 sides has an interior angle sum of 2880 degrees.
How do you find the exterior angle of a Heptagon?
51.43∘ is the measure of each exterior angle in a regular heptagon.
How many interior angles does a heptagon have?
seven interior angles
Properties of Heptagon It has seven sides, seven vertices and seven interior angles.
What is the formula for the sum of interior angles in 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.
How many sides does a polygon have if the sum of the interior angles is 2880 {\ circ ∘?
So if the sum of your interior angles is 2880, you have an 18-sided polygon.
How many sides does a polygon have if the sum of the interior angles is 2340 {\ circ ∘?
15 sided
Here sum of interior angels is 2340 degrees. Therefore, the polygon is 15 sided.
What is the sum of a 20-Gon?
3240 degrees
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.
What is the sum of the measures of the interior angles of a 20 sided figure enter your answer in the box?
The sum of the interior angles of a regular n-gon is given by the formula (n-2)180. Hence, in our case n=20 and we have the answer of 18(180)=3240 degrees.
