Round to the nearest tenth if necessary. Find the sum of the measures of the interior angles of a decagon. Answer by Alan3354(30993)   (Show Source): You can put this solution on YOUR website!In a regular 13-gon, each interior angle measures____degrees, and each exterior angle measures___degrees. Round to the nearest tenth if necessary. ------------ The sum of the exterior angles is 360º for ALL polygons. Each exterior angle = 360/13 =~ 27.7º Each interior angle = 180 - 27.7 = 152.3º ---------------------- Find the sum of the measures of the interior angles of a decagon. Sum = (n-2)*180 = 8*180 = 1440º
