I can't remember the details, but I don't feel too bad as you'll get more out of it by working them out yourself. The idea is that you can do a transformation of the coordinates to make z = 0, so the target is on your level. You know (or show) that the best angle here is 45 degrees, and pull that back to your original coordinate system to get your answer. This provides a possible explanation for why you're always aiming up, as halfway between vertical and "really far down" is still above the horizontal.
