A ramp 10 feet in length rises to a loading Platform that is 4 feet off the ground. What is the angle of elevation of the ramp in degrees?

Do I use the law of cosines? When I do though I'm getting a little confused what to do.

    sine = opposite/hypotenuse

    sin (angle) = 0.4

    PERIMETER=2(L+B)
    =
    2(63+42)
    =210
    TOTAL COST=210*32
    =672
