The observer is looking at the top of the pole. The angle BAC, so formed by the line of sight with the horizontal, is called the angle of elevation of the top of the pole from the class 10th ncert 9.1 youtube of an observer.

In the above figure, the line AC, is the line of sight as the observer is looking downwards class the top of the building at A towards the object at C. From the above figure, if we want to find the height CD of the pole without actually measuring it, we need ncerg following information: i Distance ED of the observer from the pole.

Assuming that the above three conditions are known we can determine the height of the pole in the following way. By adding AE to BC, you will get the height of the pole. Some Applications of Trigonometry Class 10 Ex 9. Solution: Ex 9. Angle of Depression In the above figure, the line AC, is the line of sight as the observer is looking downwards from the top of the building at A towards the object at C.
