You need to have an angle and a side that are opposite each other. You have a 121 degree angle that needs a side b. OR you could use the law of sines given you have an angle C across from the side of 25. 
If lower case letters represent sides and upper case letters represent angles, then you have to have one full set to do law of sines. Have to have an aA, bB, or cCno matter what. If that makes any sense.

You have to have one of those fractions be completely known + one part of one of the other fractions to use the lawof sines.
