NCERT Solutions for Class 10 Maths Chapter 9 Some Applications of Trigonometry-

In chapter 8, we have studied about trigonometric ratios. In this chapter, we will study some ways in which trigonometry is used in our daily life or in other words we can say that we will discuss the application of trigonometry. Trigonometry is one of the most ancient topics studied by scholars all over the world. This chapter contains only one exercise with 16 questions, based on the practical application of trigonometry. The NCERT Solutions for Class 10 Maths Chapter 9 Some Applications of Trigonometry are designed by our subject experts to help students in their preparation of CBSE Class 10 Board exam. These NCERT solutions are the detailed explanation of questions of class 10 NCERT maths textbook.

NCERT Solutions for Class 10 Maths Chapter 9 Some Applications of Trigonometry is the continuation of chapter 8 Introduction to Trigonometry as here we will study the application of trigonometry.  Trigonometry is used in navigation, geography, construction of maps, determining the position of an island etc. In this chapter, we will learn how trigonometry is used for finding the distances and heights and various objects, without actually measuring them. This chapter introduces new terms like the line of sight, angle of depression and angle of elevation.

• The line of sight- It is an imaginary line drawn from the observer's eye to the object viewed by the observer.
• The angle of elevation-  The angle of elevation of an object viewed by an observer, is the angle formed by the line of sight with the horizontal level when the object is above the horizontal level, • The angle of depression- The angle of depression of an object viewed by an observer, is the angle formed by the line of sight with the horizontal level when the object is below the horizontal level.
