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.
