An aeroplane flies due north from airport P to ... - JAMB Mathematics 2003 Question

An aeroplane flies due north from airport P to Q and then flies due east R. If Q is equidistant from P and R, find the bearing of P and R
A
90o
B
135o
C
225o
D
270o
correct option: c

Since PQ = QR, Δ PQR is a right angle isosceles triangle

∴ ∠PQR = 45o

=> The bearing of P from R = 180 + 45

= 225o
