Best ResponseYou've already chosen the best response.0it says use the law of sines to find angle B, but you cannot find angle B yet

Best ResponseYou've already chosen the best response.0you want to use \[\frac{\sin(B)}{b}=\frac{\sin(A)}{a}\] but you can't because you do not know \(b\)

Best ResponseYou've already chosen the best response.0what you really need to do is find angle C first that you can do using the law of sines, since you know 3 out of the four numbers for the ratio needed

Best ResponseYou've already chosen the best response.0\[\frac{sin(C)}{19}=\frac{\sin(40)}{13}\] is where you have 3 out of the four numbers

Best ResponseYou've already chosen the best response.0so \[\sin(C)=\frac{19\times \sin(40)}{13}\] making \[C=\sin^{1}\left(\frac{19\times \sin(40)}{13}\right)\]
