Curse you speedy math fails. Anyway, I believe, in problem 3, you could just do reverse tangent if your calc supports that, if so just do tan-1 36 over 35 (opposite over adjacent) If not, we’ll have to go the long way. Tan31 is opposite (x) over adjacent (35) which would come out to be 35tan31 = BC. Now that you know BC (sorry I don’t have a calc on me) you can do cos(B) = BC over 36 to get your answer.
