The accurate scale drawing shows the positions of two mobile phone masts, $$\(A\)$$ and $$\(B\)$$. A third mobile phone mast, $$\(C\)$$, is put up. $$\(C\)$$ will be on a bearing of $$\(115^{\circ}\)$$ from $$\(A\)$$. $$\(C\)$$ will be $$\(20 \mathrm{~km}\)$$ from $$\(B\)$$. (c) Find the position of $$\(C\)$$. Mark this point with a cross $$\((x)\)$$ and label it $$\(C\)$$. (3)
