Previously, we have studied that trigonometry is a branch of mathematics that deals with the relationships between sides and angles of triangles. We know how trigonometry plays a key role in solving numerous problems that exist in the real world.

On one side, trigonometry is extensively used by astronomers for finding the distance between the heavenly bodies like the sun, the moon, and the stars on the other side it has great applications in preparing maps, geography, engineering, and navigation. In this chapter, we will learn the use of trigonometry in the measurement of heights and distances which cannot be measured directly, i. Also, most probably for the first time, you will be introduced to a few important terms like Angle of Elevation, Angle of Depression, etc.

In this chapter, you will learn about some interesting ways to implement trigonometry and solve real-life problems. This chapter has only one exercise. The questions are based on real-life applications of trigonometry. You will have to visualize and mathematically represent it to solve the problems.

Questions from this chapter are frequently asked in various competitive examinations. With little understanding of various terms used and basics of trigonometry, one can easily solve the problems related to this chapter. The angle of elevation of the cloud is not equal to the angle of depression of its reflection. Refer to these solutions as you solve the problems to have a better understanding.
