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.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 180
Concept used : sin A = perpendicular/hypotenuse.
Solution :
According to question ,
From the figure, Sin P = (height of kite)/(length of string)
sin 30° = 90/(length of string)
Length of string = 90/Sin 30°
Length of string = 180 m
Hence required length of string is 180 m.
