The angle of elevation of the top of a building from the top of another building is 30°. If the height of the first building is 20m and the distance between them is 10√3 m, what is the height of the second building?
Q1. The angle of elevation of the top of a building from the top of another building is 30°. If the height of the first building is 20m and the distance between them is 10√3 m, what is the height of the second building?
Answer: 30 m
Explanation: tan(30°) = (h - 20) / 10√3. So, h - 20 = 10. Thus, h = 30 m.
