Sum of measures of interior angles nonagon
Web16 Nov 2024 · The sum of the interior angles of a polygon are (n-2)*180, where n is the number of sides. So the sum of the interior angles of a nonagon where n = 9 is (9-2)*180 = 1260. The sum of the given 7 interior angles is 974, leaving 1260 - 974 = 286 for the remaining two equal angles.' Thus each of those angles must measure 286/2 = 143. WebThe sum of the interior angles in a nonagon is (9 – 2) × 180 = 7 × 180 = 1260°. The known angles add up to 96 + 100 + 190 + 140 + 113 + 127 + 155 + 122 = 1043. To find the final missing...
