The sum of the angles in a nonagon total 1260 degrees.
The nine interior angles of a nonagon add up to 1260 degrees
A nonagon is a 9 sided polygon and its 9 interior angles add up to 1260 degrees
The sum of the interior angles of a nonagon is calculated using the formula (n - 2) × 180°, where n = 9. Substituting the values, we get (9 - 2) × 180° = 1260°. This means the total sum of all interior angles in a nonagon is 1260 degrees. Each interior angle in a regular nonagon is 140 degrees.
The sum of the interior angles of a nonagon is (9 - 2) x 180o = 7 x 180o = 1260o In a regular nonagon, each interior angle is 1260o ÷ 9 = 140o
