Learning Goal:

As shown, three forces act on the tip of a pole. $F_1=-60i+105j+25klb.F_2=120lb$ and forms the following angles with the $x,y,$ and $z$ axes, respectively: $=55\mathrm{.}2,=63\mathrm{.}6,$ and $=133\mathrm{.}7.F_3=90lb,$ forms the angle $=28$ with the $z$ axis, and forms the angle $=35$ between the $x$ axis and the projection of $F_3$ in the $xy$ plane.Part $A-$ Resultant of adding $F_1$ and $F_3$

Find the resultant of adding $F_1$ and $F_3.$ Express your answer in component form.

Express your answers, separated by commas, to three significant figures.
