Can you give me any reason why I would give you the value for A?

Hello, and welcome to FMH! 
I'm going to assume you just have no idea where to begin, which is why you have no work of your own to show. I would begin by writing:
[MATH]\tan(x)=2\implies \sin(x)=2\cos(x)[/MATH]
What do you get upon substituting for \(\sin(x)\) into the given equation?
