\end{figure} Figure 1 shows the forces acting on a particle, \(P\). These consist of a 20 N force to the South, a 6 N force to the East, an 18 N force \(30 ^ { \circ }\) West of North and two unknown forces \(X\) and \(Y\) which act to the North-East and North respectively. Given that \(P\) is in equilibrium,
  1. show that \(X\) has magnitude \(3 \sqrt { } 2 \mathrm {~N}\),
  2. find the exact value of \(Y\).
