Best ResponseYou've already chosen the best response.0OK. The way I'm used to using the sine law is as follows:\[\frac{ \sin \left( A \right) }{ a } =\frac{ \sin \left( B \right) }{ b }\]. Is this the way you have it?

Best ResponseYou've already chosen the best response.0@ospreytriple yeah i did that but you have to rearange to the way i had it and then do s\[sinb=\frac{ 17\sin47 }{ 13 }\]

Best ResponseYou've already chosen the best response.0I think there's an error in the rearranging. You have \[\frac{ \sin \left( B \right) }{ b }=\frac{ \sin \left( C \right) }{ c }\]To isolate sin(C) you would multiply both sides of the equation by c, giving\[\frac{ c \sin \left( B \right) }{ b }=\sin \left( C \right)\]Make sense?

Best ResponseYou've already chosen the best response.0OK. So solve\[\sin \left( C \right)=\frac{ 17 \sin \left( 47 \right) }{ 13 }\]
