I can't figure out my girlfriend's homework. Here is a crude image in paint of what it looks like.
angle I is 15 degrees.
We figure that both angles II and III are 75 and 105 degrees respectively because of the right angle formed by the pole atop the slope. We are trying to find how long X1 and X2 are.
The image is a pole on a slope with two wires holding it down, we're trying to figure out how long the wires are. The problem is that we cannot figure out how we can find the other angles. I think that the 15 degrees comes into play again, but I can't figure out how.
