Answer:


(70)/(sin40^(\circ))

Explanation:

We are given that

Height of the kite from the ground=h=70 feet


\theta=40^(\circ)

We have to find the length of kite string in term of trigonometric ratios.

Let length of string=x

We know that


sin\theta=(Perpendicular\;side)/(hypotenuse)

Using the formula


sin40^(\circ)=(h)/(x)


sin40^(\circ)=(70)/(x)


x=(70)/(sin40^(\circ))

Hence, the length of kite string=
(70)/(sin40^(\circ))
