Find the angle of depression from top of a 500 m long chairlift with a vertical height of100 m

  • maths methods -

    Here height = 100 m.
    length of cable = 500
    angle of depression, θ = sin-1(100/500)

    If the length of the chairlift is measured horizontally, then θ would be tan-1(100/500)
