  1. 1

    ramp = rise ÷ sin(angle)

    = 24 ÷ sin(20°) = 24 ÷ 0.342

    70.2 in
  2. 2

    run = ramp × cos(angle)

    = 70.2 × 0.94

    65.9 in
  3. check: run² + rise² = ramp²

    65.9² + 24² = 4924

    70.2 in

rise = vertical height · run = horizontal footprint · ramp = the sloped surface itself
