1 Easy The compass bearing N40°E written as a true (three-figure) bearing is:
2 Easy The true bearing of due East is:
3 Medium Measured clockwise from North, the true bearing of the south-west direction is:
4 Medium A hiker walks $8$ km on a true bearing of $060°$. How far EAST of the start is she? (East component $= 8\sin 60°$)
5 Hard For the same hiker (8 km on bearing $060°$), how far NORTH of the start is she? (North component $= 8\cos 60°$)
6 Hard A ship sails from port $P$ to port $Q$ on a true bearing of $070°$. The bearing of $P$ as seen from $Q$ (the back bearing) is:
