    Remember that weight (a force) always points straight down, and that the normal force is perpendicular to the surface the object makes contact with. Once you have these forces figured out, the rest is given in the question.

    Is this correct?


    Fcosθ = N

    f = μN
    f = μFcosθ

    Fsinθ = mg + μFcosθ

    Using that equation above Fsinθ = mg + μFcosθ, I tried to solve of F and then use Fdcosθ to get the work, I got the answer wrong.
