The base of the triangle is 67.2 m which is opposite to degrees theta which is 50. You are trying to find the hypotenuse of the triangle so you would use the Sin formula.
Anyway, as i was saying, you have to use the formula for Sin in order to get the hypotenuse. [input]67.2*sin(50)[/input] Which gives you the length of the hypotenuse, which is what you are looking for.
