Best ResponseYou've already chosen the best response.1Does it make sense up to here $$ \Large \frac{\sin 24^o}{77}= \frac{\sin C}{162} $$

Best ResponseYou've already chosen the best response.1so we are using just two parts of the three part ratio

perl

Best ResponseYou've already chosen the best response.1you can do that since they are equal

Best ResponseYou've already chosen the best response.1we don't know `sin B` and `b` anyway at this point , yet

Best ResponseYou've already chosen the best response.1and we have to solve for C?

perl

Best ResponseYou've already chosen the best response.1$$ \Large{ \frac{\sin 24^o}{77}= \frac{\sin C}{162} \\~\\ \iff \\~\\ \sin 24^o \times 162 = 77 \times \sin C \\~\\ \iff \\~\\ \frac{\sin 24^o \times 162}{77} = \sin C }$$

Best ResponseYou've already chosen the best response.1okay. and how do we isolate C?

Best ResponseYou've already chosen the best response.1Now try to 'solve' the triangle (find all side lengths and angles). You can find angle B using the fact that three angles of any triangle add up to 180. Then use law of sines one more time to find side b, or alternatively you can use law of cosines
