# Calculate all parameters of a triangle from some known partial lengths and angles

I have the problem described in this image (not to scale): http://i.imgur.com/owWVUmj.png

A (partial cathetus), B (small, vertical cathetus) and C (which forms a 90º angle with hypotenuse) are known lengths (A=3, B=8, C=2 meters, inches, or whatever). I need to obtain the exact values of all sides and angles. The most important length I need is X, but I could calculate it myself once I know the at least one of the angles or lengths.

Could someone please tell me how to calculate at least one of the sides or angles?

Thank you very much.

I would try to use en.wikipedia.org/wiki/Intercept_theorem –  ulead86 Jan 25 '13 at 11:30
