So, you know the angle and the oposite leg and look for adjacent leg?

 

(setq theY (/ theX (/ (sin theAngle) (cos theAngle))))

The above trigonometric formula works only in right-angled triangles - for your case need to split your current triangle in right-angled triangles and perform calculations in each to get the appropriate formula.

Can you post a sketch of your case?
