Let the height of the building is BC, the height of the transmission tower which is fixed at the top of the building be AB.
D is the point on the ground from where the angles of elevation of the bottom B and the top A of the transmission tower AB are 45° and 60° respectively.
The distance of the point of observation D from the base of the building C is CD.
Combined height of the building and tower = AC = AB + BC
Trigonometric ratio involving sides AC, BC, CD, and ∠D (45° and 60°) is tan θ.
In ΔBCD,
tan 45° = BC/CD
1 = 20/CD
CD = 20
In ΔACD,
tan 60° = AC/CD
√3 = AC/20
AC = 20√3
Height of the tower, AB = AC - BC
AB = 20√3 - 20 m
= 20 (√3 - 1) m
