Question

$A$, $B$ and $C$ are three points on level ground. The bearing of $B$ from $A$ is $065{}^\circ$ and $\angle ABC=30{}^\circ$. It is given that $C$ is $4$ km due south of $A$. Calculate the bearing of $C$ from $B$, distance of $BC$, shortest distance between $A$ and $BC$.

Accepted Answer

(i) $215^\circ$ (ii) $BC=7.25\text{ km}\text{ (3 s.f.)}$ (iii) $2.29\text{ km}\text{ (3 s.f.)}$
