Let's call the angle formed by the ramp and the ground θ. Then, based on the trig ratios, we know that the sin of θ is 11/40. This let's us set up an equation to solve for θ.
sin θ = 11/40
θ = arcsin(11/40)
θ ≈ 15.962 degrees
So the angle between the ramp and the ground is approximately 15.962 degrees.
