1. The problem statement, all variables and given/known data Find a by using The Law of Sines by knowing that c=12, angle A=42o, angle C=69o. 2. Relevant equations (sin A)/a=(sin B)/b=(sin C)/c 3. The attempt at a solution I tried putting it in, but all I got was this correct, but useless equation: 6511/7990=383/470 I did it 1 more time, but still it wasn't successful. Please Help!
