Let there be a n sided regular polygon. Since, the sides of a regular polygon are equal, the sum of interior angles of a regular polygon = (n − 2) × 180° For example, the sides of a regular polygon are 6. So, the sum of interior angles of a 6 sided polygon = (n − 2) × 180° = (6 − 2) × 180 ... If the sum of the interior angles of a polygon is 1440 ∘, then it has ___ sides. Q. If the sum of interior angles of a polygon is 1440 ∘ , then it has ___ sides.There are 180 (N – 2) degrees in a polygon if we add up the measures of every interior angle: Sum of Interior Angles of an N-gon = 180 (N – 2) degrees. For example, a polygon with N = 22 sides has 180 (22 – 2) = 180 (20) = 3600 degrees. That is, the sum of all interior angles in a 22-sided polygon is 3600 degrees.Step-by-step explanation: sum of interior angles of any polygon = (n-2)×180. ( here n is the number of sides) number of sides in a nonagan = 9. Therefore, equation = (9-2)×180. 7×180. 1260. therefore, the sum of interior angles of a regular nonagon is 1260°.The measure of each interior angle of a polygon is 150. Find the number of sides in the polygon Let be the number of sides. Since all angles of a regular polygon are congruent, the sum of the interior angles can be expressed as 150 150 = −2∙180 150 =180 −360 −30 =−360 =12 There are 12 sides.Nonagon is a 9 sided polygon. Exterior angle = 360 ÷ 9. = 40. Interior angle + exterior angle = 180. Interior angle = 180 - 40. = 140°. Sum of interior angles = 140° × 9. = 1,260°. arrow right.Sum of Interior Angles of a Regular Polygon. Let there be a n sided regular polygon. Since, the sides of a regular polygon are equal, the sum of interior angles of a regular polygon = (n − 2) × 180° For example, the sides of a regular polygon are 6. So, the sum of interior angles of a 6 sided polygon = (n − 2) × 180° = (6 − 2) × 180 ... About Transcript To find the interior angle sum of a polygon, we can use a formula: interior angle sum = (n - 2) x 180°, where n is the number of sides. For example, a pentagon has 5 sides, so its interior angle sum is (5 - 2) x 180° = 3 x 180° = 540°. Created by Sal Khan. Questions Tips & Thanks Want to join the conversation?
