There are 3 forces acting on him, the weight of him and the sledge acting straight down W, the push from the slope acting perpendicular to the slope P and the resistive forces on the sledge and the boy acting up the slope.

Im completely stumped on how to do this, ive got to find the magnitude of the resistive force and determine the component of weight W that acts perpendiculay to the slope so if someone could answer the question and show how they did it i would be really grateful. Thanks
