The diagram shows the position of each of three buildings in a town.
72° + 9° = 81°
The bearing of the Hospital from the Art gallery is 072°.
So the bearing is 081
The Cinema is due East of the Hospital.
The distance from the Hospital to the Art gallery is equal to the distance from the Hospital to the Cinema.
Work out the bearing of the Cinema from the Art gallery.
