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 Answer: Option C
Explanation

Since PQ = QR, Δ PQR is a right angle isosceles triangle
∴ ∠PQR = 45o
=> The bearing of P from R = 180 + 45
= 225o
