WebDec 24, 2015 · Explanation: The formula for calculating the sum of the interior angles of a regular polygon is: (n - 2) × 180°. Where n is number of sides. sum of angles = (n - 2) × … WebJun 5, 2024 · So you can find the size of the exterior angles of a regular polygon quite easily: If there are 18 sides (n = 18), then each exterior angle is: 360° n = 360° 18 = 20°. The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line. ∴ each interior angle is 180° − 20° = 160°. Answer link.

How to calculate the sum of interior angles of a n-gon - YouTube

WebTo find the measure of the interior angle of a 24-gon, we can use the same formula: Interior angle = (180(n-2))/n. Substituting n=24, we get: Interior angle = (180(24-2))/24 … Webb) If each interior angle is 157.5˚, then each exterior angle is 180˚!157.5˚=22.5˚. Since the sum of the exterior angles of any n-gon is 360˚, 360˚÷22.5˚! 16sides. Example 4 Find the area of a regular 7-gon with sides of length 5 ft. Because the regular 7-gon is made up of 7 identical, isosceles 7 good study habits
