Normally, capital letters are angles, small letters are sides. I have no idea what you are presenting.
In triangle you must have 3 elements.

3 sides OR

2 sides and 1 angle OR

1 side and 2 angles

You can not solve triangle with 2 elements.
If it's a right triangle, just use the pythagorean theorem. (Asq + Bsq = Csq
