The scale sketch shows two islands labelled $A$ and $B$. Scale: $2\text{ cm to }1\text{ km}$.
(a)[1]
Express the scale $2\text{ cm}$ to $1\text{ km}$ as $1:n$.
(b)[1]
Use measurement to determine the bearing of $B$ from $A$.
(c)[2]
Island $C$ is located on the northern side of $AB$. It lies $3\text{ km}$ from $A$ and $2.5\text{ km}$ from $B$. Use a ruler and a pair of compasses to construct triangle $ABC$.
