A man from the top of a high tower sees a car moving towards the tower at an angle of depression of After some time, the angle of depression becomes . The distance travelled by car during this is
m
Finding the distance travelled by car:
Step 1: Considering the theorem
We know, for a right-angle triangle with angle ,
Step 2: Applying the theorem to the given triangle,
For the triangle ,
m
For the triangle
m
Step 3: Finding the distance travelled by car
For the given problem, the length of is the distance travelled by the car,
m
Therefore, the distance travelled by the car is m
Hence, Option (B) is the correct option.
