number of angles = number of sides 180 - 120 = 60 (calculating the exterior angle) 360 / 60 = 6 There are 6 sides. Hope this helps! :)

formula for internal angles of a n gon is (n-2)180/n so it has 120 on each of the angles 120=(n-2)180/n times both sides by n 120n=180n-360 minus 180n both sides -60n=-360 divide both sides by -60 n=6 6 sides
