This is the basic and conceptual question from trigonometry of height and distance in which we are to find the length of the string if a kite is flying at a height of 75 meters from the ground level, attached to a string inclined at 60o to the horizontal.

Book – RS Aggarwal, Class10, chapter 14, question no 2.

## Let AB=75= Height of Pole

and AD be the length of the wire

From △ABD

sin60o=AB/AD

## ⇒√3/2=75/AD

## ⇒AD=150/3

⇒150/1.73 (Take3=1.73)

=86.6 m
