1. The problem statement, all variables and given/known data So, I am brushing up on my trig...and now I feel a bit slow. I am attempting to use the law of sines for the attached problem and keep getting the wrong angle. For some reason I never learned the law of sines/cosines before today... 2. Relevant equations A/Sin(a) = B/Sin(b) = C/Sin(c) 3. The attempt at a solution 4/sin(27)=5/sin(theta) then.... arcsin(5*sin(27)/4) = theta = 34.6 I know this is the angle beside it, but I don't know what I am doing wrong. Any help would be great!
