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
