Question

a person is flying a kite and an angle of elevation 60° the length of the thread is 30 metres find the height of the flying kite from the ground​

Answer 1

Step-by-step explanation:

theta=60°

hypotenuse=30m

Therefore

sin theta = p/h

sin60 = p/30

√3/2=p/30

30√3 / 2 = p

15√3 = p

Therefore height of the flying kite from the ground is 15√3m.

Mark as brainliest.

Answer 2

Answer:

let the height be x metres

lenght of thread =30 metres

sin 60= perpendicular/hypotenuse

sin 60= √3/2

hypotenuse =30

√3/2=x/30

x=√3*30/2

x= √3*15

x=1.732*15

x= 25.98 metres

therefore the kite is 25.98 metres above ground
