Question

A person in flying a kite at an angle of elevation α and the length of thread from his hand to kite is l draw diagram for the following situation

Answer 1

Hint: Kite attached to thread flies in the sky making some angle with the horizontal and this particular angle made is called the angle of elevation and when we see any object on ground from the upper side then the angle made is called the angle of depression.
The line along which this kite is being seen in the sky is called line of sight.


Complete step by step solution:
Properties of kite:
The two angles are equal where the unequal sides meet.
It can be viewed as a pair of congruent triangles with a common base.
It has 2 diagonals that intersect each other at right angles.
The longer or main diagonal bisects the other diagonal.
A kite is symmetrical about its main diagonal.
The shorter diagonal divides the kite into 2 isosceles triangles.
The angle of elevation is the angle between the horizontal line of sight and the line of sight up to an object. For example, if you are standing on the ground looking up at the top of a mountain, you could measure the angle of elevation. The angle of depression is the angle between the horizontal line of sight and the line of sight down to an object. For example, if you were standing on top of a hill or a building, looking down at an object, you could measure the angle of depression. You can measure these angles using a clinometer or a theodolite. People tend to use clinometers or theodolites to measure the height of trees and other tall objects.

To make the diagram use the concept of height and distance.

\[\alpha \to \]angle of elevation
\[l \to \]Length of thread

Note:This question is solved only with the help of the height and distance concept.
The angle of elevation is the angle between the horizontal line of sight and the line of sight up to an object.
