@idioticpickle Yeah! Yeah! I keep telling Richard to let me do one of these by myself! I'm sick of carrying him through these things. --Harvey

The formula for the interior angles is 180-e (exterior angle)

[@cuberarjun8878]

I know the formula which is : (n-2)×180. Here n refers to number of sides

If you think math is hard, then you are bad at it.

[@joy4229]

You need a better understanding of yourself.
