    Angle α = 10.36° ≈ 10°

    Step-by-step explanation:

    In this case we have right triangle the ramp is hypotenuse and vertical distance is right side of triangle.

    In accordance with the definition of the sinus we have

    sinα = 80/445 = 0.1797 = > α = arc sin 0.1797 = 10.36°

    Angle of elevation α = 10.36° ≈ 10°
