You can just put it straight into a calculator...

Most calculators with just give you an approximations of course.

I got an approximation of 0.425 radian. II would do it over and make sure I had to identical answers before I accepted it though.

Are you looking for an exact answer?

Np, I have been trying for a few hours, and still don't know so I understand if it's hard. :)
