solutions :
(a) 79°24′
Fore bearing = 79° 24′
Back bearing = FB +180° ( as the FB is less than 180° )
= 79°24′ +180°
= 259°24′
(b) 354°24′
Fore bearing= 354°24′
Back Bearing = FB-180° ( as the FB Is greater than 180° )
= 354°24′ – 180°
= 174°56′
(c) 178°04′
Fore bearing = 178°04′
Back bearing=FB +180° ( as the FB is less than 180° )
=178°4′ +180°
= 358°04′
(d) 204°12′
Fore bearing = 204°12′
Back Bearing = FB-180° ( as the FB Is greater than 180° )
= 204 °12′ – 180°
= 24°12′
