240

and 120

60 is not the answer because in the first quadrant, all trigonometric functions yield positive values.... Only in the 2nd and 3rd quadrant does cosine function yield negative values..

I think she wants the answers in radical form...

6. MichelCarroll Group Title

4pi/6 and 8pi/6

How you get a degree into radian for is to multiply the degree by $\pi \div180$

So 60 degrees in radians would be $60*\frac{ \pi }{ 180 }$
