Question

An Aeroplane when flying at a height of 4000 m from the ground, passes vertically above another Aeroplane at an Instant when the angles of elevation of two plains from the Same point on
the ground are 60⁰ and 45° respectively. Find the vertical
distances between the Aenoplane of that instant .​

Answer 1

Step-by-step explanation:

An Aeroplane when flying at a height of 4000 m from the ground, passes vertically above another Aeroplane at an Instant when the angles of elevation of two plains from the Same point on

the ground are 60⁰ and 45° respectively. Find the vertical

distances between the Aenoplane of that instant .

Answer 2

And the angle of elevation of this plane from the same point D is 60∘. Let this angle be ∠BDC=45∘. Hence, the vertical distance between the aeroplanes at that instant is 1690.599m
