These problems involve an inverse trig function

Explanation:

The exact inverse trig function you want to use depends on the values you're given.

It sounds like Arccos(\theta) might work for you, if you have the magnitude of the vector (hypotenuse) and the distance along the y-axis, which you could assign to be the adjacent side.
