Answer:
A. Building A, it is around 100.69 feet taller than building B.
Step-by-step explanation:
Since building A is 120 feet away at and elevation of , then:
Tan =
Where x is the height of the building at the horizontal plane.
x = Tan × 120
= 100.692 feet
For building B at the same elevation,
Tan =
x = Tan × 60
= 50.346 feet
Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
