An escalator lifts people to the second floor of a building, 20 ft above the first floor. the escalator rises at a 30 degrees angle. to the nearest foot, how far does a person travel from the bottom to the top of the escalator?

40 feet

Step-by-step explanation:

hypotenuse=  2 times shorter leg

     s= 2 times 20

     s=40

so a person will travel 40 ft from the bottom to the top of the escalator.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
