Find the total interior angle first using: (n-2)*180 Where n are the number of sides.
OpenStudy (saifoo.khan):
So this is 6 sided. We will use: (6 -2)* 180
OpenStudy (anonymous):
4*180=720
OpenStudy (saifoo.khan):
Correct, now: 720 = all interior angles. 720 = 135+ 62+ 151 + 140 + n + n + 6 Solve for n.
