Question

Amit, standing in a horizontal plane, finds a bird flying at a distance of 200m from him at an elevation of 30º. Deepak standing on the roof of 50m high building, finds the angle of elevation of the same bird to be 45º.Amot and Deepak are on opposite sidea of the bird.

Answer 1

Answer:

50√2m

Step-by-step explanation:

let distance from deepak to bird be 'DE'

sin30° = (50 + CE)/200

1/2 = (50 + CE)/200

CE = 50 m

Sin 45° = CE/DE

1/√2 = 50/DE => DE = 50√2m
