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.

  • math -

    No, it is a right triangle
    sin angle = 4/10

  • math -

    I tried that and it said that it was the wrong answer.

  • math -

    Well I get 23.58 degrees.

  • math -

    you use sin^-1 then do 4/10
