Best ResponseYou've already chosen the best response.0Not so fast. So we know that \(a=50\) degrees. \(\cos a=\frac BC\). \(C\) we know is \(90\). So yes, to solve for B, you would use \(B=90\cos a\).

Best ResponseYou've already chosen the best response.0you multiply 50x90 right

Best ResponseYou've already chosen the best response.0No, you multiply 90 by cos 50.

Best ResponseYou've already chosen the best response.0Alright, do you know what an operation is? \(\sin x\) and \(\cos x\) are like machines into which you put a number \(x\) and retrieve a value. So do \(\cos50\) first.

Best ResponseYou've already chosen the best response.0I have no idea what you're talking about. You sound confused. Do you know what \(\sin x\) is?

anonymous

Best ResponseYou've already chosen the best response.0No, even more importantly, \(\sin x\) is an operation performed on \(x\). You're used to operations like \(+,,\times,\div\), but \(\sin x\) is an operation like that. You can't just move the \(\sin\) around.
