Yes. Just remember, SOHCAHTOA. Sin is Opposite/Hypotenuse. Cosine is Adjacent/Hypotenuse, and Tangent is Opposite/Adjacent. :)

You would use cos. So, \(\ \huge cos(x)=\frac{8}{BA} \).

Close. So what it would like is \(\ \huge cos(43)=\frac{8}{BA} \). Then you'll multiply by the variable BA, and to isolate the variable, divide by cos43. So what you'll be doing is: \(\ \huge length BA=\frac{8}{cos43} \). Does that make sense to you?
