So I started out by doing (n2)(180) And I substituted n for 16 because n is the number of sides. so.. (162)(180) 14(180) =2520

And then I tried to find out what the measure of the interior angles was.

2520/16=157.5 So are you saying that 157.5 is the measure of an interior angle?

That makes each side become 180 for interior!?! whaaa...makes no sense..

oh..so then how do I do this?

Sorry, its been a long time _ Here, i found this: Exterior angles always add up to 360 no matter how many sides. So to find an interior angle, it's easiest to find the exterior angle and subtract it from 180 since interior + exterior = 180 So 1 16gon: 360 / 16 = 22.5; 180  22.5 = 157.5 degrees
