how do I solve this question: tan(B)=0.6249

Thanks for that website reference, Rampager1998....however, I think this question involves some trig.......

tan(B)=0.6249     ...to find this angle use the tangent inerse....so we have

atan(.6249) = B = about 32 degrees  ... note that this could also be a 3rd quadrant angle. i.e., about 212 degrees.

Sorry wrong post.

No prob....I thought you might have meant your answer for another question.......
