sin(35)=84/Hypotenuse

0.57358=84/H cross multiply

0.57358H=84 divide both sides by .57358

H=84/0.57358

H=146.45 feet - distance walked on the escalator.

Let x ft be the distance a person travels on the escalator stairs.

sin35 = 84/x

x = 84/sin35 ≈ 146.45 

A person travels 146.45ft on the escalator stairs.
