Question

The length of the string of a kite flying at a height of 100 m from the ground and angle of elevation 60 degree is

Answer 1

Answer:

by theorem of 30-60-90

Step-by-step explanation:

100=√3/2×hypo

hypo=200/√3

therefore length of string is 200/√3

Answer 2

Answer:

Draw a right triangle with B at right angle and C as elevation angle of 60 degree.

Step-by-step explanation: Now,

sin 60 degree = Perpendicular/Hypotenuse

 $\sqrt{3}$/2 = AB/AC

$\sqrt{3}$/2 = 100/AC

$\sqrt{3}$*100/2= AC

AC = 50$\sqrt{3}$m

So,

The length of the string of kite flying at a height of 100 m from ground and angle of elevation 60 degree is 50$\sqrt{3}$m.
