A kite is attached to a string. Find the length of the string (in m) when the height of the kite is 90 m and the string makes an angle of 30° with the ground.
Answer & explanation
Correct answer: option 1
⇒ Sin \({30}^\circ\) = \(\frac{90}{AC}\)
⇒ \(\frac{1}{2}\) = \(\frac{90}{AC}\)
⇒ AC = 90 x 2
⇒ AC = 180m.
