As observed from the top of a 75 m high light house above the sea level, the angles of depression of two ships are 30° and 45°
respectively. If one ship is exactly behind the other on the same side of the light house and in the same straight line, find the distance between the two ships. (use √3 = 1.732)
This question is exactly same as Ex 9.1, 13 of Chapter 9 Class 10 in the NCERT Book.
Please check the answer and video here
In the link above, the answer is
Distance = 75 (√3 – 1)
Putting √3 = 1.732
Distance = 75 (1.732 – 1)
Distance = 75 × 0.732
Distance = 54.9 m
