    sin θ = 8/100 => 2/25

    sin(θ) = 2/25

    25 sin(θ) = 2

    Solutions:

    θ ≈ 6.2832 n + 3.0615, n element Z

    θ ≈ 6.2832 n + 0.080086, n element Z

    The gradient of a stretch of road is generally defined as the vertical height compared to the horizontal distance.

    i.e. tanθ = 8/100 => 2/25

    Hence, θ = 4.8°

    However, some texts will define this as vertical height compared to diagonal run or distance.

    i.e. sinθ = 8/100 => 2/25

    Hence, θ = 4.6°

    Note: Engineers and Surveyors will use the former

    Note: In the UK if you see a sign that says ''1 in 10'' or 10% it means 1 vertical for every 10 horizontal

    8% = 2/25

    sin(x) = 2/25

    sin⁻¹(x) = 0.08

    θ=4.58° or 5° Answer//

    Comment : 8% = 8 / 100 = tangent of the angle
