A kite is soaring at an altitude of 75 meters above the ground, with its string temporarily secured to a point on the ground. The angle of elevation of the string relative to the ground is 30 degrees. Given that the string remains taut, what is the length of the string?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 150 m.
Height (AB) = 75 m
Kite string length = AC
⇒ sin 30° = 75/AC
⇒ 1/2 = 75/AC
⇒ AC = 150 m
