Im stuck on a question from the P1 Textbook, page 247, Question 38, which reads:
" A ship sails 3 nautical miles from P to Q on a bearing 071 degress and then 4 nautical miles from Q to R on a bearing 292 degress. Calculate the distance PR and the bearing of R from P".
I've sketched a litlte diagram, which I think is right, but theres no way of knwing (I dont have a sacnner so I cant scan it and post it here) . I dont know how I would go onto work out the rest of the question, especially part B. Part A, working out the distance, I've tried Sine rule but it doesnt seem to work. Any help would be appreciated.
