The bearings of P and Q from a common point N are 020° and 300° respectively. If P and Q are also equidistant from N, find the bearing of P from Q.
040°
070°
280°
320°
설명
From the diagram above, <PNQ = 80º
But < PQN = <NPQ = 50º ( base <s of isosceles triangle PQN)
Therefore, the bearing of P from Q = 070º
