WebApr 27, 2024 · For given example, We need to find the sum of 7 of the interior angles of a regular decagon. Number of sides of decagon (n) = 10. Using the formula of sum of interior angles, ⇒ S = (n - 2) × 180°. ⇒ S = (10 - 2) × 180°. ⇒ S = 1440°. This means the sum of all interior angles of a regular decagon is 1440°. We know, there are 10 ... WebEach interior angle of a regular dodecagon is equal to 150°. This can be calculated by using the formula: \(\frac{180n–360} {n}\), where n = the number of sides of the polygon. In a dodecagon, n = 12. ... In a regular … WebWeb Thus, The Number Of Diagonals In A Decagon Is 35. Since the sum of the angles of a triangle is 180°, the sum of the interior angles of a dodecagon is 8 × 180° = 1440°.
