A kite is flying at a height of 123 m. The thread attached to this assumed to be stretched straight and makes an angle of 60º with the level ground. The length of the string is (nearest to a whole number):
Show answer & explanation
Correct answer: C
Explanation
Correct Answer is option 3 i.e. 142 m
|
Understanding |
|
Given: Vertical height of the kite from ground = 123 m Angle made by thread from the level ground = 60° |
|
Application |
|
In the figure: Sin60 = AB/AC = 123/AC √3/2 = 123/AC AC = 246/√3 = 142.03 or 142 m |
