A kite is flying at a height of 50 metre. If the length of string is 100 metre then the inclination of string to the horizontal ground in degree measure is

1. 90
2. 60
3. 45
4. 30

Correct Option: D

AB = Height of kite = 50 metre
OB = length of thread = 100 metre

∴ sin BOA =	AB	=	50	=	1	= sin 30°
	OB		100		2

∴ ∠BOA = 30°
