Find The Sum Of The Measures Of The Interior Angles Of Each Convex Polygon. A polygon with 13 sides 32. Substitute n 23 in.
A polygon with 18 sides has an interior angle sum of 2880 digrees. A810 b1080 c1620 d2880. Use the Polygon Interior Angles Sum Theorem to find the sum of its interior angle measures.
Each interior angle of a regular polygon n-2180n where n is the number of sides in the polygon.
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. Find the sum of the measures of the interior angles of a convex polygon with 18 sides. Where n is the number of sides of the polygon. The sum of the angles in any polygon is equal to the number of sides in the polygon minus two all multiplied by 180 degrees.
