seems to me like you don't even need to worry about the first guy wire at all. You need a function that deals with the Opposite Over Adjacent.

I would redraw it using only what I need: We'll say the hypotenuse is x. That is the opposite. The reference angle is 64º. The adjacent line is 18.1m. Tan = Opposite / Adjacent tan64º = x/18.1m 2.05 = x/18.1m 37.11m

Thank you for the help! I just have one "on the side" question ... why does it make sense to multiply 2.05 by 18.1?

Because the righthand side, x/18.1m, when multipled by 18.1m gives x (by the definition of division), and what's done to the righthand side needs to be done to the lefthand side also.
