Q13MEnergy, Work and PowerFree sample

A block is pulled for a distance of $50\text{ m}$ along a horizontal floor, by a rope that is inclined at an angle of $\alpha^{\circ}$ to the floor. The tension in the rope is $180\text{ N}$ and the work done by the tension is $8200\text{ J}$ . Find the value of $\alpha$ .
