What if θ was zero? According to your formula, this would give a torque of Fd (because cos(0) = 1). But, if you look at the picture, if θ = 0, shouldn't the torque be 0 as well? You are just pulling straight out; this shouldn't turn the bolt at all.
Hint: is θ really the angle between the force and the displacement?

I figured out that the answer is 1.89810^{2}N
F=45F*m/(0.300m*sin(52.6°))
