help!?!?! What is mBCA? for the triangle shown!

OpenStudy (anonymous):

This triangle is an equilateral, meaning that all the sides are the same measurement, and all the angles are the same measurement. If all the angles in a triangle add up to 180 degrees, and a triangle has three sides and three interior angles, then it should be 180 divided by 3, which is 60, so angle BCA is 60! :D
