You might want to try graphing 212 degrees 40 minutes.  In which quadrant do you find this angle?  Once you've drawn a ray from the origin representing this angle, draw in the "opposite side" and the "adjacent side."  Which acute angle, either positive or negative, between the x-axis and your ray, has the same sine as does 212 degrees 40 minutes?

anonymous · Answer

would it be in the third quadrant?

anonymous · Answer

and the opposite would be negative..

mathmale · Answer

Yes indeed.  Strictly speaking, you could solve this problem without drawing a diagram, but do it anyway, please.  Yes, the opp side would be negative.  Good!
