A wrench $0\mathrm{.}500m$ long is applied to a nut with a force of $80\mathrm{.}0N.$ Because of the cramped space, the force must be exerted upward at an angle of $60\mathrm{.}0$ with respect to a line from the bott through the end of the wrench. How much torque is applied to the nut?

a$.4\mathrm{.}56N*m$

b$.11\mathrm{.}8N,m$

C$.14\mathrm{.}2N*m$

d$.34\mathrm{.}6N*m$
