Answer 1

Answer:

Step-by-step explanation:

In ΔABC,

Tan60 = H/x

=>  √3 = H/x

=> H = x√3 ----------------- (1)

In ΔABD,

Tan30 = AB/BD = H/(x + 20)

1/√3 = H/(x+20)

=> x + 20 = H√3  

=> x + 20 = (x√3)√3   (∵ H = x√3)

=> x + 20 = 3x

=> 2x = 20

=> x = 10 m.

H = x√3 = 10√3 m.

Thus the height of tower = 10√3 m and width of canal = 10 m.
