The length of the sky lift is 3.387.05 ft Step-by-step explanation; By an online search, i found that the sky lift rises at an angle of 20.75 degrees. Then we can think on a triangle rectangle, such that: One cathetus is 1200ft, this is the opposite cathetus to the angle of 20.75° The length of the ski lift would be the hypotenuse of this triangle rectangle. Then we can use the relationship: Sin(a) = opposite cathetus/hypoteuse. such that: a = 20.75° opposite cathetus=1200ft then: sin(20.75°) = 1200ft/hypotenuse hypotenuse =1200ft/sin(20.759) =3.387.05 ft The length of the sky lift is 3.387.05 ft
