) Bearing of P from Q = 270o +15o
= 285o
Bearing of Q from P = 90o + 15o
= 105o
2) Bearing of P from Q = 056o
Bearing of Q from P = 180o + 56o
= 236o
3) Bearing of P from Q = 90o +25o
= 115o
Bearing of Q from P = 270o + 25o
= 295o
4) Bearing of P from Q = 180o +50o
= 230o
Bearing of Q from P = 050o
5) Bearing of P from Q = 220o
Bearing of Q from P = 040o
