Step-by-step explanation:
bro can you tell me in simplest format for the ans
We use the trigonometric function for this case. An escalator is an inclined path. We form a right triangle since we have given the value of the height. The height from the first floor to second floor is called the adjacent while the travelled distance of the people is called the hypothenuse. We use cosine function because we are given in terms of adjacent and hypothenuse. The ratio of cosine function is
cos x = a/h
where x is the angle
Solving for h,
h = a/(cos x) = 21/(cos 30) = 24.25 ft

Only 1 time because your talking about division so u have to divide 8 into 8 which it only goes in 1 time:)
Answer:
x=3
Step-by-step explanation:
4x-8=4
4x=12
4x/4=12/4
