Q1
In downtown Austin, a student uses a small mirror on the ground to measure a building's height. The student's eye is 1.6 m above the ground and stands 2 m from the mirror. The mirror is 25 m from the base of the building. Assuming the line of sight to the building's top reflects off the mirror, use similar triangles to find the building's height. Round to the nearest meter.
