The ms says 135 or 45 depending on the diagram...first, in darren's diagram, the 90km line is less than the 54 km line, u have to at least roughly make it longer...
plus check the diagram i have attached, it shows how the angle is 135 too..
i have a gce-o lvel past papers book and i just saw this question is in that book as a sample question paper, there , the answer says - 28.9 as i have exactly explained..

OK, I will correct you because you are wrong. Read the question - it says the ship is at a bearing of 315 from the lifeboat at 0600 hours. Your diagram shows that the ship is at a bearing of 315 from the lifeboat at 0730 hours instead of at 0600 hours.
