A kite is flying at a height of 45√3 m. The thread attached to it is assumed to be stretched straight and makes an angle of 60° with the level ground. The length of the string is?

45 m 60 m 90 m 45√3 m

90 m

AC = length of string θ = 60° Now, sin 60° = \(\frac{AB}{AC}\) \(\frac{\sqrt {3}}{2}\) = \(\frac{45\sqrt {3}}{AC}\) AC = 2 × (45) = 90 m
