NCERT Solutions for Class 10 Math Chapter 9 - Some Applications Of Trigonometry

Step-by-step explanation:

Mathematics NCERT Grade 10, Chapter 9: Some applications of trigonometry - It is a short chapter in which students will study about some ways in which trigonometry is used in life around us. Trigonometry is the most ancient subjects studied by scholars all over the world. Astronomers have used trigonometry to calculate distances from the earth to the planets and stars.

In section 9.2 the topic Height and Distances is discussed. Various terms are explained in this part of the chapter. Terms discussed:

Line of sight is the line drawn from the eye of an observer to the point in the object viewed by the observer.

Angle of elevation of the point viewed is the angle formed by the line of sight with the horizontal when the point being viewed is above the horizontal level.

Angle of depression of a point on the object being viewed is the angle formed by the line of sight with the horizontal when the point is below the horizontal level.

7 solved examples are included in this chapter to make the same concept comprehensible to students in which problems of height and distance calculation is covered.

This only exercise in the chapter is a vast exercise containing 16 questions. In the first few questions, the height of various objects is unknown and students have to calculate the same. In some questions, the width of the object is to be calculated. Other questions demand calculation of the distance between two objects. Some questions are figure based questions.

Thus, to conclude we can say that the height or length of an object or the distance between two distant objects can be determined with the help of trigonometric ratio
