Answer:
50 ft
Step-by-step explanation:
The side lengths in a 30-60-90 triangle have the ratios 1 : √3 : 2. The longest side is 2 times the length of the shortest side.
In this geometry, that means the length of the escalator is 2 times its height, so is ...
x = 2(25 ft)
x = 50 ft . . . . . distance a person travels

Answer: 1 plane</h3>
Think of a flat sheet of paper. If you draw a line through that paper, you can rotate the paper around the line to lake it spin like a fan blade. This suggests infinitely many planes go through the same straight line. If you add a point somewhere off the line, then the plane becomes fixed and there is only one plane that goes through both the line and the point at the same time.
