a mall escalator rises 84 feet at 35 angle find the distance a person travels on the escalator stairs
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.
