Prove that the height of the tower is 6 m. The height or length of an cheap bass boats for sale in alabama 80 or the distance between two distinct objects can be determined with the help of trigonometric ratios. The observer is looking at the top of the pole. The angle BAC, so formed by the line of Class 10 Maths Ch 9 Ex 9.1 Word sight with the horizontal, is called the angle of elevation of the top of the pole from the clsss of an observer.

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 Mathx. From the above figure, if we want to find the height CD of the pole without actually measuring it, naths need the 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.
