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
