Question

The High Roller Ferris wheel in Las Vegas, the tallest in the world, is elevated 2 m above ground. When a car reaches the highest point on the ferris wheel, its altitude from ground level is 168 m. How far away from the center, horizontally, is the car when it is at an altitude of 120 m?

Answer 1

the radius of the wheel is ... (168 - 2) / 2 ... m

the altitude of the center is ... radius + 2 ... m

(horizontal distance)^2 + (distance above center)^2 = radius^2
