Answer:
The kite forms a right angled triangle with hypotenuse of 50 ft. The height of the kite above the ground is the opposite of 60° angle.
Using the sine rule, Sin 60 = Height of the kite above the ground/Hypotenuse
Therefore, Height of the kite above the ground = Hypotenuse*Sin 60 = 50 *Sin 60 = 43.3 ft
