Question

To estimate the height of a monorail track, your friend holds a cardboard square at eye level. Your friend lines up the top edge of the square with the track and the bottom edge with the ground.

Answer 1

To estimate the height of a monorail track visually using a cardboard square, align the top edge of the square with the track and the bottom edge with the ground.

Step-by-step explanation:

To estimate the height of a monorail track visually, your friend is using a cardboard square as a frame of reference. By aligning the top edge of the square with the track and the bottom edge with the ground, your friend can estimate the height of the track based on the relative position of the square.

For example, if the square is held at eye level and the top edge aligns with the track and the bottom edge aligns with the ground, the height of the track would be the height from the ground to the bottom edge of the square.
