\includegraphics[max width=\textwidth, alt={}, center]{5b10afa1-1c45-4370-a0e6-ad8fd626df9a-3_638_839_269_653} Three coplanar forces of magnitudes \(5 \mathrm {~N} , 8 \mathrm {~N}\) and 8 N act at the origin \(O\) of rectangular coordinate axes. The directions of the forces are as shown in the diagram.

1. Find the component of the resultant of the three forces in
   (a) the \(x\)-direction,
   (b) the \(y\)-direction.
2. Find the magnitude and direction of the resultant.
