Question

The angle of depression of a car parked on the road from the top of a 150 m high tower is 30°. The distance of the car from the tower (in metres) is

`(A) 50sqrt3`

`(B) 150sqrt 3`

`(C) 150sqrt2`

`(D) 75`

Solution

Correct answer: A

Let AB be the tower and BC be distance between tower and car. Let θ be the angle of depression of the car.
According to the given information,

`In triangleABC,`

`tan theta =`

`BC=150/sqrt3=(150sqrt3)/3=50sqrt3`

Hence, distance between the tower and car is  `50 sqrt3`

.

  Is there an error in this question or solution?
