A radio transmission tower is 170 feet tall. How long should a guy wire be if it is to be attached 15 feet from the top and is to make an angle of 27 with the ground? Give your answer to the nearest tenth of a foot.

I am confused because of the whole "15 feet from the top" thing. I can't visualize what it is asking. If someone can help me with how the triangle is drawn, I can get it from there. thanks so much.
