Best ResponseYou've already chosen the best response.1So 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

Best ResponseYou've already chosen the best response.1And then I tried to find out what the measure of the interior angles was.

Best ResponseYou've already chosen the best response.0Int angle=(n2)* 180/n

Best ResponseYou've already chosen the best response.0Now just divide by the number of sides

Best ResponseYou've already chosen the best response.1R u sure? @zaynahf for some reason I thought it was wrong to do that.

Best ResponseYou've already chosen the best response.0then u forgot to divide /n or number of sides in this case 16 i think

Best ResponseYou've already chosen the best response.12520/16=157.5 So are you saying that 157.5 is the measure of an interior angle?

Best ResponseYou've already chosen the best response.1And then.. 360/16 =22.5 for exterior angle?

Best ResponseYou've already chosen the best response.1Oh! 14 for the triangles?

Best ResponseYou've already chosen the best response.1That makes each side become 180 for interior!?! whaaa...makes no sense..

Best ResponseYou've already chosen the best response.1oh..so then how do I do this?

Best ResponseYou've already chosen the best response.0Sorry, 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
