3 legged stool angles

I have a mechanism that resembles a 3 legged stool. One of the legs has a fixed length. The other 2 can change length. I need to calculate d and e that will produce a desired pitch and roll angle. When (d) and (e) are 0, all 3 legs are the same length (c) and the pitch and roll angles are 0. The pitch and roll angles are limited to +/- 45 deg.

(see attached diagram)
