Boy Mow Chau's answer is more elegant and transferable.

But my answer happens to be correct, he made an insignificant numerical error in the cross product (I do that all the time in other questions, so I emphasize I am correct again in this question right here).

This approach also requires less prior knowledge to appreciate.
