33.7° West of South is bearing of D from B
Step-by-step explanation:
Distance Between B & D
= √( 30² + 45²)
= 15√4 + 9
= 15√13
= 54 km
Angle of D from B = Tan⁻¹( 45/30) = 56.3°
Bearing of D From B = 56.3° South Of West
or 90 - 56.3° = 33.7° => 33.7° West of South
33.7° West of South is bearing of D from B
