Question

5. A kite is attached to a string. If the kite is flying at a height of 45 m and the string
makes an angle of 30° with the ground, then the length of the string is
(a) 60 m
(b) 90 m
(c) 120 m
(d) 225 m​

Answer 1

Explanation :

Let, the length of the string be 'x' m .

sin 30⁰ = 45 / x

1 / 2 = 45 / x. ( sin 30⁰ = 1 / 2 )

x = 90 m

therefore, correct option no. is b) 90 m
