Two forces are acting on the hook, as shown in the figure.

Note that force $F,$ lies on the $y-$z plane. Remember to include units in your final answer!

a$)$ Write forces $F_1$ and $F_2$ in Cartesian form

b$)$ Calculate the resultant $F_R$ of forces $F_1$ and $F_2$

c$)$ Find the magnitude and the coordinate direction angles of the resultant force

$F_2=200lb$
