Part D $-$ Finding the required force to produce a desired moment

In the figure below, $F_1=3\mathrm{.}30kN,F_3=1\mathrm{.}30kN,$ and $d=790mm.($Figure $5)$What force $F_2$ is required for the net couple moment on the triangle to

be $290N*m$ clockwise?

Express your answer to three significant figures and include the appropriate units.
