for angles in degrees ...
Hello. This should be an easy one, but the answer I'm getting doesn't match the answer in my text book, so I just want someone to help me either confirm it as a misprint or show me what I did wrong:
The question is:
Evaluate the following with a calculator, give the answer in degrees rounded to two decimal places:
I get: -13.30 degrees
My text book says: 166.70 degrees
