A kite flying at a height of 120 m is attached to a string which makes an angle of 60o with the horizontal. What is the length (in m) of the string?
Answer & explanation
Correct answer: option 4

⇒ Sin \({60}^\circ\) = \(\frac{120}{AC}\)
⇒ \(\frac{√3}{2}\) = \(\frac{120}{AC}\)
⇒ AC = \(\frac{120 × 2}{√3}\)
⇒ AC = \(\frac{240}{√3}\)
⇒ AC = 80√3
