Question 764651
Consider this a right angled triangle.
String = Hypotenuse.
Height the kite is above the ground = Opposite side.
Using Sin ratio
Sin = Opposite/Hypotenuse
Sin(70) = Opposite/245ft
Opposite = 245 * sin(70)
Opposite = 230.23ft
This is the height the kite is above the ground.
Hope this helps.
