Question

The shadow of a tower standing on the level ground is found to be 45 root 3 metre longer when the sun altitude is 30 degree then when it was 60 degree find the height of the tower

Answer 1

Answer:

height of the tower = 67.5 m

Step-by-step explanation:

The shadow of a tower standing on the level ground is found to be 45 root 3 metre longer when the sun altitude is 30 degree then when it was 60 degree find the height of the tower

Let say Height of Tower = H

Tan 30  = H/Shadow length 1

=> Shadow Length = H√3

Tan 60 = H/Shadow length 2

=> Shadow length 2 = H/√3

H√3  -  H/√3    = 45√3

Multiplying by  √3

3H - H = 45*3

=> 2H = 135

=> H = 67.5

the height of the tower = 67.5 m
