1. P, Q and R are three buildings. A car began its journey at P, drove to Q, then to R
and returned to P.
The bearing of Q from P is 058° and R is due east of Q.
PQ = 114 km and QR = 70 km.

(i) Draw a clearly labelled diagram to represent the above information. Show
on the diagram
(a) the north/south direction
(b) the bearing 058°
(c) the distances 114 km and 70 km.

(ii) Calculate
(a) the measure of angle PQR
(b) the distance PR
(c) the bearing of P from R
