Answer: The sum of the measures is 1260. ... Angles of a regular nonagon Since each of the nine interior angles in a regular nonagon are equal in measure, each interior angle measures 1260° ÷ 9 = 140°, as shown below. Each ...To calculate the sum of the interior angles of a nonagon, use the following formula: Sum of Interior Angles = (n - 2) × 180°. In this equation, represents the number of sides in the polygon. For a nonagon, n = 9. Sum of Interior Angles = (9 - 2) × 180° = 7 × 180° = 1,260°. Regardless of whether the nonagon is regular or irregular, the ...

In order to find an exterior angle for a regular polygon which contains n sides and n angles, the total sum of its interior angles should be found using the formula {eq}S = 180^o(n - 2) {/eq}. Dividing this sum by the number of angles would produce the magnitude of one angle: ... Find the sum of the interior angles of a nonagon. A. 140 B. 1,620 ...The sum of the interior angles is 1440°.
