A tower T 1 of height 60 m is located exactly opposite to a tower T 2 of height 80 m on a straight road. From the top of T 1 , if the angle of depression of the foot of T 2 is twice the angle of elevation of the top of T 2 , then the width (in m) of the road between the feet of the towers T 1 and T 2 is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Let, the width of the road the road is d.
If the angle of the elevation is 
, then
, here 20 is the difference between the heights of T 1 and T 2 .
Given that, the angle of depression is twice of the angle of elevation.
