Use tan= opposite ∕ adjacent .
The angle subtended by the tower gives a relation between height and distance.
The depression angle from a higher point gives another relation.
Solve the two equations to find the horizontal distance.
Solution
Let the horizontal distance be d.
From ground point:
tan‌30∘=‌

H

d

⇒H=‌

d

√3

From point at height h :
tan‌60∘=‌

h

d

⇒d=‌

h

√3

Thus,
d=h‌cot‌60∘
