WebAll of the angles are going to be the same. And you actually know what that measure is. If you have three things that are the same-- so let's call that x, x, x-- and they add up to 180, you get x plus x plus x is equal to 180, or 3x is equal to 180. Divide both sides by 3, you get x is equal to 60 degrees.
