One early escalator built in 1896 rose at an angle of 25 degrees. The vertical lift was 7 feet. Estimate the distance d a person traveled on this escalator

The distance d that a person traveled on the escalator=16.56 feet

Step-by-step 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
