A boat sails 8 km north from P to Q and then sails 6 km west from Q to R. Calculate the bearing of R from P. Give your answer to the nearest degree.
217o
323o
037o
053o
Correct answer is B
tan θ = oppadj=RQQP=68
tan θ = 0.75
θ = tan−1(0.75)=36.87o
∴ The bearing of R from P = 360o - 36.87o = 323o (to the nearest degree)
