No, I'm saying that cotangent of an angle in the 2nd quadrant must be negative.

well my answer was negative, but the teacher circled the positive one...

]]>If theta is is quadrant II, the cosine is negative and sine is positive. Thus, tanget is negative and so cotangent must be negative.

So your saying that you take the answer I got which is -5/12 and add another negative since in quadrant 2, tan is negative, and you get 5/12?
