Find The Sum Of The Measures Of The Interior Angles Of Each Convex Polygon Hexagon. Hexagon 165 720 16 -gon 165 2520 ART Jen is making a frame to stretch a canvas over for a painting. For the nonagon shown find the unknown angle measure x.
The sum of the measures of the interior angles of each triangle is 180 so the sum of the measures of the interior angles of the octagon is 6 Â180 1080 sides of the polygon. Find the number of sides in the polygon. Interior Angles of A Polygon.
Substitute n 12 in.
Convex polygons interior angles are less than. 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. What is the measure of each interior angle. Substitute n 20 in.
