EXERCISE 1 (B) ) 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
