Would anyone be kind enough to help on this question?
answer is E - 290, but I keep getting F - 315.

Thank you

It says "R is 5 km away from Q on a bearing of 155°" .... if you misread it as bearing of R from P is 155 then you end up with 315!

Thank you for your posts.
I have the exact same diagram, but I kept measuring the clockwise angle between QR and PR,
instead of the angle between the upwards vertical from R and PR.
sorry to waste your time on such silliness
thank you
