The two forces shown act in the $x-y$ plane of the T$-$beam cross section. If it is known that the resultant $R$ of the two forces has a

magnitude of $3\mathrm{.}6$ kN and a line of action that lies $16$ above the negative $x-$axis, determine the magnitude of $F_1$ and the orientation $$ of

$F_{}.$

Note that there are two pairs of answers to this question.

The answer pair with the smaller value for $F_1.$

$F_1=ikN$

$=,i,$@

The answer pair with the larger value for $F_1.$

$F_1=,-,-{?}^{kN}$

$=,$
