In this topic, you will study about the line of sight, angle of elevation, horizontal level, and angle of depression.

All these terms are explained in a detailed form along with some solved examples based on it. These solved examples Ch 9 Of Maths Class 10 75 based on the terms line of sight, angle of elevation and angle of depression will help you to understand Ch 9 Of Maths Class 10 75 Ch 9 Of Maths Class 10 75 Ch 9 Of Maths Class 10 75 the concepts thoroughly. How to Calculate Height and Distance? Trigonometric ratios are used to find out the height and the distance of the object. For example: In figure 1, you can see a boy looking at the top of the lampost.

AB is considered as the horizontal level. This level is stated as the line Ch 9 Of Maths Class 10 75 parallel to the ground passing through the viewer's eyes. AC is considered as the line of sight. An inclinometer or Clinometer is a device usually used for measuring the angle of elevation and the angle of depression.

Let us recall some trigonometric ratios which help to solve the questions based on class 10 maths Ch 9 Of Maths Class 10 75 Chapter 9. Trigonometry Ratios.

The ratio of the sides of a right-angle triangle in terms of any of its acute angle triangle is known as the trigonometric ratio of that specific angle. Sine - The sine of Ch 9 Of Maths Class 10 75 an angle is stated as the ratio of the opposite side perpendicular side to that angle to the hypotenuse side. Cosine- The cosine of an angle is stated as the ratio of the adjacent side to that angle to the hypotenuse side. Tangent - The tan of an angle is stated as the ratio of the opposite side perpendicular side to that angle to the side adjacent to that angle.

Cosecant- It is the Ch 9 Of Maths Class 10 75 reciprocal of sine. Secant- It is the reciprocal of cosine. Cotangent- It is the reciprocal of tangent. The Ch 9 Of Maths Class 10 75 following trigonometry ratio table is used to calculate the questions based on applications of trigonometry class 10 NCERT solutions.

Sin C. Cos C. Tan C. Not defined. Cosc C. Sec C. Cot C. Now, you must have understood all the important topics and terms covered in each section of class 10 maths chapter 9.
