I had the same problem (the reason was thread '213977 from SilverSprite ;-) )
I used the following link :"http://www.mathe-aufgaben.de/mathehilfen/mathe-abitur/Trigo/16201%20LEBLA%20Trig%20nrw%20Dreiecke.pdf"
Sorry,it's in German, but you should be able to use the formulas.
Your problem is SSS, that is 3 sides(S) are known, have fun.
If you need some translation, just yell.
