Answer:
The distance d that a person traveled on the escalator=16.56 feet
Explanation:
To estimate the distance traveled by the elevator we can use the formula;
Sin ∅=Opposite side/Hypotenuse side
where;
∅=25°
Opposite side=vertical lift=7 feet
Hypotenuse=distance, d
replacing;
Sin 25=7/d
d×sin 25=7
d sin 25=7
d=7/Sin 25
d=7/0.4226
d=16.56 feet
The distance d that a person traveled on the escalator=16.56 feet
