You can put this solution on YOUR website! 8 of the exterior angles add up to 360. Therefore, each one is 360/8, or 45 degrees.
The interior angle is its supplement, or 135 degrees.
You can put this solution on YOUR website! The general rule for an n-sided polygon is (n-2)*180/n. So, if n is 8, then:
6*180/8=135
The interior angles are 135 degrees each!!!!!!!!!!
