    OR did you take that: In semi equilateral triangle: The hypotenuse = 2 ( shorter leg) and the longer leg = square root of 3 times the shorter leg ?? * I think it's easier to use it in this problem.

    hmm SOH stands for Sine equals Opposite over Hypotenuse. B is the opposite side and C is the hypotenuse
