hints: * All angles of an equilateral triangle are equal * For any triangle, the three angles add to 180 degrees (using the previous hint, you can say x+x+x = 180 and solve for x) * you'll use the inscribed angle theorem http://static.blog.beatthegmat.com/mba/files/2012/05/E89000b.png which says that the arc measure is double the inscribed angle (the inscribed angle cuts off the arc from the circle)
