OP, I get an answer of 222.817 degrees. Let me know if you get this answer, if not show your working and we'll see where you've gone wrong.

You may find it easier, albeit less precise, to work in decimals rather than fractions/multiples of Pi, simply from a mental comprehension standpoint.
For reassurance, D.P. and Hodders methods are correct.

To those chastising the OP saying that this is easy stuff, please remember that everyone is different, and in the same way, all schools are different. I can only remember being taught the problem solving analytical skills for things like this in Year 9.
