5. Given are the following forces:
\[
\begin{array}{l}
A=300 \mathrm{~N}, \mathrm{~N} 45^{\circ} \mathrm{E} \\
\mathrm{~B}=200 \mathrm{~N}, 35^{\circ} \mathrm{S} \text { of } \mathrm{W} \\
\mathrm{C}=500 \mathrm{~N}, 60^{\circ} \mathrm{N} \text { of } \mathrm{E} \\
\mathrm{D}=400 \mathrm{~N}, 37^{\circ} \mathrm{W} \text { of } \mathrm{N}
\end{array}
\]
Find the magnitude and direction of the resultant force using:
a) Polygon method (Graphical method/scale drawing).
NOTE: Use graphing paper
b) Rectangular-component method (Analytical method).
