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.

180 $90\sqrt{3}$ 45 $60\sqrt{3}$

180

⇒ Sin \({30}^\circ\) = \(\frac{90}{AC}\) ⇒ \(\frac{1}{2}\) = \(\frac{90}{AC}\) ⇒ AC = 90 x 2 ⇒ AC = 180m.
