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

math 
Jason,
I tried that and it said that it was the wrong answer.

math 
Damon,
Well I get 23.58 degrees.

math 
June,
you use sin^1 then do 4/10
