Best ResponseYou've already chosen the best response.0the inner sum of angles is 180(n2) (n number of angles) so if 180(n2)=144, then n=10 so 144*10=1440

Best ResponseYou've already chosen the best response.0Another way to figure out without memorizing formulas is to know that the angle formed at the center of the shape is 180144 = 36. Because there must be 360 degrees at the center, it must therefore be true that the shape has 360/36 = 10 sides.
