how much work is being done a bookshelf being pulled 5 meters at an angle of 37 degrees from the horizontal? The magnitude of the component of the force that does the work is 43 Newtons

I assume the bookshelf is being pulled up a 37 degree slope and that a 43 N force does the pulling in the same direction, up the slope. In that case the work done is 43*5 = 215 Joules.
