    If someone can help me work out the problem we can do it together. I'm not looking just for an answer, I want to learn!

    well think about the trigonometric functions. If the angle on the top right is a right angle. Lets call the distance from moon to sun z. well what function (sin cos or tan) will represent the all of the variables?

    Would we try to find the cosine? Because we need to find Z and Y?

    ok, so you know that you can take the sin(x) = y/z or opposite over hypotenuse. Now given that you have the values of x and y, z is simply, by the algebraic simplification, y/sin(x). z is the hypotenuse.
