ANSWER:
Step 1 of 3
(a)
Here we need to determine the vertical height of the building that can be seen in the mirror. The building is
behind the person holding mirror. The mirror is at
in front of the eyes and the mirror at height
.
By taking the height to distance ratio of mirror and building, we have
