CBSE X Maths Some Applications of Trigonometry
A boy whose eye level is 1.3 m from the ground, spots a balloon moving with the wind in a horizontal level at some height from the ground. The angle of elevation of the balloon from the eyes of the boy at any instant is 60°. After 2 s, the angle of elevation becomes is 29√3 m/s, then find the height of the balloon from ground.
