A kite reaches a vertical height of 75 m from the ground. The string attached to the kite is inclined at 60° to the horizontal. The length of the string is:
Show answer & explanation
Correct answer: A
Explanation
Height = 75 meters
The string makes an angle of 60° with the horizontal.
Let the length of the string = L
sin 60° = Height / String
√3/2 = 75 / L
L = 75 × 2 / √3 = 150/√3 = 50√3 meters
