Question

The angles of depression of the top and bottom of a building 50 meters high as observed from the top
of a tower are 30° and 60° respectively. Find the height of the tower, and also the horizontal distance
between the building and the tower.​

Answer 1

Answer:

Let AB be the building of 50m. ... Let the distance between the building and tower be AC. The angle of depression to the top of the building =∠QDB=30∘ . Similarly the angle of depression to the bottom of building =∠QDA=60∘ .
