Best ResponseYou've already chosen the best response.1There's 7 triangles in 9gon, each triangle's interior angles sum is 180 Thus, a 9gon's interior angle sum is 7* 180 = 1260 degrees We want to know how many degrees there are in each interior angle, since a 9gon has 9 interior angles, 1260/9 = 140 degrees.
