WebIn a regular polygon all interior angles are equal in measure. So we can find each interior angle by dividing the sum of interior angles by the number of sides. Sum of interior angles Number of sides = 2340 ∘ 15 [Substitute the values] = 156 ∘ [Divide] Hence, each interior angle measures 156 ∘. Example 6: Find the measure of the unknown angle. WebA heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees. Same thing for an octagon, we take the 900 from …

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 = 165 degrees. Therefore, the measure of the interior angle of a 24-gon is 165 degrees. 4. To find the number of sides of a polygon when given the sum of the interior ... WebWe get. So, the sum of the interior angles of an 11-gon is 1620 degrees. Regular 11-gons: The properties of regular 11-gons: All sides are the same length (congruent) and all interior angles are the same size (congruent). To find the measure of the angles, we know that the sum of all the angles is 1620 degrees (from above)... WebThe sum of all the exterior angles of a polygon is always 360 degrees. From the given ratio, we can formulate an equation: x+2x+3x+4x+5x = 360. 15x = 360. x = 24. As x=24, the measure of each of the exterior angles … 7g rainbow colony heroine name
