RS Aggarwal Solutions for Class 10 Maths Chapter 14 Height and Distance

Height is the measurement of an object in the vertical direction, and distance is the measurement of an object from a particular point in the horizontal direction. So if we know the height of the object and the linear distance, we can easily find out the angle by the trigonometric formula. It is given by tan = Height / distance. Height and Distance: One of the main application of trigonometry is to find the distance between two or more than two places or to find the height of the object or the angle subtended by any object at a given point without actually measuring the distance or heights or angles. Trigonometry is useful to astronomers, navigators, architects and surveyors etc. The angle of elevation of the sun that is better known as altitude angle can also be found by the same method. In this chapter from RS Aggarwal students can get to learn some problems on heights and distances. Problems should not involve more than two right triangles. Angles of elevation/depression should be only 35 degree, 45 degree and 60 degree.
