Answer:
The length of the string is 32.56 feet (Approx) .
Step-by-step explanation:
As given
A kite is 37 feet in the air and string forms an angle of 62 degrees .
Now by using the trignometric identity.
![sin\theta = \frac{Perpendicular}{Hypotenuse}](https://tex.z-dn.net/?f=sin%5Ctheta%20%3D%20%5Cfrac%7BPerpendicular%7D%7BHypotenuse%7D)
As shown in the figure given below.
![\theta = 62^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%2062%5E%7B%5Ccirc%7D)
Perpendicular = AB
Hypotenuse = AC = 37 feet
Put in the identity .
![sin\ 62^{\circ} = \frac{AB}{AC}](https://tex.z-dn.net/?f=sin%5C%2062%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7BAB%7D%7BAC%7D)
![sin\ 62^{\circ} = \frac{AB}{37}](https://tex.z-dn.net/?f=sin%5C%2062%5E%7B%5Ccirc%7D%20%3D%20%5Cfrac%7BAB%7D%7B37%7D)
![sin\ 62^{\circ} = 0.88\ (Approx)](https://tex.z-dn.net/?f=sin%5C%2062%5E%7B%5Ccirc%7D%20%3D%200.88%5C%20%28Approx%29)
Put in the identity
![0.88 = \frac{AB}{37}](https://tex.z-dn.net/?f=0.88%20%3D%20%5Cfrac%7BAB%7D%7B37%7D)
AB = 0.88 × 37
AB = 32.56 feet (Approx)
Therefore the length of the string is 32.56 feet (Approx) .
