Best ResponseYou've already chosen the best response.0one way to solve is : using law of cosine find "c" then you can find number of triangle \[b^2+c^2a^2=2(b)(c) \cos(A)\\3616+c^2=2(6)(c)\cos(30)\]

Best ResponseYou've already chosen the best response.0or using law of sine \[\frac{ \sin(A) }{ a }=\frac{ \sin(B) }{ b}\\\frac{\sin30}{4}=\frac{\sin(B)}{6}\\sin(B)=\frac{3}{4}\]
