Each interior angle of a regular pentagon has a measure of 2x+4°. What is x? 52°. The measures of four exterior angles of a pentagon are 57°, 74°, 56°, and 66°. What is the measure of the remaining angle? 287°.Sep 24, 2023 · Therefore, the sum of the interior angle of a convex nonagon is. 1260∘ 1260 ∘. . Note: The expression. (n − 2)180∘ ( n − 2) 180 ∘. is taken because for a polygon with ‘n’ sides, if we join one vertex to all other vertices, we will have triangles formed out of this construction and the number of triangles formed is given by.
The sum of the angles in a triangle is 180°. To find the sum of the interior angles of a polygon, multiply the number of triangles in the polygon by 180°. ExampleThe interior angles of a nonagon are shown here: The sum of these 9 angles is given by the formula: sum of interior angles = (n - 2) x 180. Where n is the number of sides. In this case, the number of sides n is 9, so the sum of the interior angles is: (9 - 2) x 180 = 1260 degrees. For a regular nonagon, all the interior angles are equal:Solution.
