To find the angle of elevation of the ramp, we can use the tangent function, which is defined as the opposite side divided by the adjacent side in a right triangle.
Let x be the angle of elevation.
Hence, tan(x) = opposite/adjacent = 2/11.
To find x, we take the arctan of both sides:
x = arctan(2/11) ≈ 10.3°.
Therefore, the angle of elevation of the ramp is approximately 10.3°.
