Thanks a lot!

1) A + B + C = 180 ............. so sin(A) = sin(B+C)

2) attack Left-hand-side and simplify the numerator and continue.......

thanks!! But I still can't seem to get the answer. I don't know what to do with the right hand side...If I were to do this problem:

Leave the RHS alone for the time being continue to simplify LHS. Tell us what do you get.thanks!! But I still can't seem to get the answer. I don't know what to do with the right hand side...

I reached cosBcosC=sinBsinC, but I don't know what to do after this. I put tanB as sinB/cosB to get this.Leave the RHS alone for the time being continue to simplify LHS. Tell us what do you get.

Never mind, I got the answer!! Turns out i was doing it right all along, except that i forgot an essential formula. Thanks again for your help, i really needed itLeave the RHS alone for the time being continue to simplify LHS. Tell us what do you get.
