Question

A kite is flying with a thread 250m long. If the thread is assumed stretched straight
and make an angle of ss with the horizontal, find the height of the kite above the
ground.​

Answer 1

answer.like that

answer.Let A be the position of the kite at a height AC

Here AB=200m

In right-angled triangle △BCA

sin50

∘

=

AB

AC

⇒0.7660=

200

AC

⇒AC=0.7660×200=153.2

∴ The height of the kite=153.2m

Answer 2

Step-by-step explanation:

Let h denote the distance of the kite from the ground level.

In the figure, AC is the string Given that

∠CAB=30

∘

and AC=200m

In the right △CAB,sin30

∘

=

200

h

⇒h=200sin30

∘

∴h=200×

2

1

=100m

Hence, the distance of the kite from the ground level is 100m.
