Tofind:the altitude of the plane using trigonometric ratio.
Answer to Problem 26E
The altitude of the plane is 3.32ft.
Explanation of Solution
Given:
Angles of elevation from
Concept used:
1 Hour=60 min
Calculation:
The figure can be drawn as right- angled triangle as shown below
In the above figure
Therefore, angles of elevation from
Use the fact that the speed of the planes is
Therefore,
In the right
For the right
From (i) and (ii) get
Therefore the altitude of the plane is 3.32ft.
