Have $1$ un:

Numeric $1\mathrm{.}67$ points

The Resultant of the two vectors below has a magnitude of $1,000lb$ and is directed along the positive $y-$axis.

$($a$)$ Draw R on the diagram. $($Show this in your submitted work ONLY.$)$

Then determine $($b$)$ the magnitude of $F_B$ in pounds and $($c$)$ then in Newtons.

Finally, find $($d$)$ the angle $($in $)$ shown needed to achieve this $R.$

Note: Do not assume A and B are at $90$ with respect to each other.

Enter you answer for $($b$)($in lb$)$ in the blank below

$866\mathrm{.}0$
