You can put this solution on YOUR website! Tangent 165 by adding 135 and 30 degrees. I get ( -1 + sqrt3/3)/1-(-1)(sqrt3/3) so -1 but that is not right. What am I doing wrong.
**
your answer: (-1+√3/3)/(1+√3/3)≠-1
Since the problem usually requires an exact answer, it should be left in this form with the radicals. You can check the answer with a calculator by comparing the value of tan 165º against the numerical value of your answer. They should be close but not exactly the same.
