So I have this problem I'm stuck on in my math class, and we've just started trig (11th grader, 12th grade math). I feel like the problem is much easier than what I'm looking at, but here's a crude drawing of the image the text book gives for the problem:

The straight lines making the 'x' shape are crossing belts (I think the textbook called them) and x is the angle measure. I messed up the motor's x and it should just be the angle of the top triangle.
So far I looked at my trig identities reference sheet, thought of using the angular speed formula (but couldn't figure out how to deal with the answer I got from it), and asked kids in the other/higher math classes, and none of them can figure it out either. Knowing the correct answer isn't necessary due to my teacher only checking completeness, but it would be nice if I knew how to do this type of problem.
