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
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Since PQ = QR, \Delta PQR is a right angle isosceles triangle
∴ ∠PQR = 45o
=> The bearing of P from R = 180 + 45
= 225o
