Question

from a point on the ground the angles of elevation of the bottom and top of a transmission tower fixed at the top of a 20m high building are 45 and 60 respectively. find height of the tower​

Answer 1

Answer:

According to question,

Height of building  L = 20 m

Angle from top of building   theta = 45 deg

Angle from top of tank     A = 60 deg

Let the height of tank be x

Thus

tan theta = L/ B

tan 45 = 20 / B

Thus 

B = 20 m

Now

tan A = x + L / B

x + L = tan 60 * 20

x  =  20 ( root 3 - 1)
