# NCERT Solutions For Class 10 Maths Chapter 9 Exercise 9.1 Some Applications of Trigonometry - PDF Download

Class 10 NCERT solutions for class 10 maths chapter 9 ex 9.1 some applications of trigonometry are completely dependent on height and distance. In order to solve this exercise, there are three terms that students need to know. The first term is the line drawn from the eye of an observer to the point in the object viewed by the observer is known as the ‘line of sight’. The second term is the ‘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. The third term is the ‘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.

All questions are derived from these three concepts with the addition of trigonometric ratios and identities. NCERT solutions class 10 maths chapter 9 ex 9.1 is made up of 15 questions on the practical application of trigonometry, which are essentially word problems. The most important thing you need to keep in mind is to draw the figures while solving the problems. This will help to make the questions easier to solve and increase the visualization benefit. The question range from simple to complex, and students will need to use their critical minds to solve them.

NCERT solution for class 10 maths chapter 9 ex 9.1 is available in a free PDF format. You can download the PDF from eSaral website and practice all the questions anytime.

## Topics Covered in Exercise 9.1 Class 10 Mathematics Questions

Here are some important topics in ex 9.1 which are described by our experienced teachers. You can check the table below.

 1 Heights and Distances
1. Heights and Distances - Trigonometric ratios are used to determine an object’s height and distance. The height is determined by the vertical length of the object and the distance is determined by the horizontal distance of the object from a specific point.

Here are some important factors regarding heights and distances:

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

2. Angle of Elevation - The 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 elevation is always above the eye level.

3. Angle of Depression - The 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. Angle of depression is always below eye level.
