The diagram indicates the positions of ships $A$ and $B$. On this diagram, $1\,\text{cm}$ stands for $30\,\text{m}$.
(a)[2]
Using measurement, determine the actual distance of $B$ from $A$.
(b)[1]
Measure the bearing from $A$ to $B$.
(c)[2]
A third ship lies at $C$. $C$ is on a bearing of $164^{\circ}$ from $A$ and on a bearing of $252^{\circ}$ from $B$. Find and mark the position of $C$ on the diagram.
