As per the problem
The escalator make a 30° angle with the floor .
The escalator have a vertical height of 36 feet.
Now draw the diagram with the given information, the diagram is attached below
From the diagram,
Horizontal length=AB=d
Distance traveled by the person on the escalator stairs=AC=l
In triangle ABC,
Again in triangle ABC, Using Pythagoras Theorem
The horizontal length needed is
The distance a person would travel on the escalator stairs is 72 ft
Answer:
Step-by-step explanation:
Te equation of line is:
y = 3x + 12
Plug x = 0 in the above equation of line, we find:
y = 3*0 + 12
y = 0 + 12
y = 12
y-intercept = (0, 12)
Plug y = 0 in the equation y = 3x + 12
0 = 3x + 12
-3x = 12
x = 12/(-3)
x = - 4
x-intercept = (-4, 0)
Distance between x-intercept and y--intercept
