Question

a kite is flying at a height of 6m above the ground. The length of its string is 10m. The other end of the string is held at t C. Find the length of BC.​

Answer 1

Answer:

the length of the string is 40

Step-by-step explanation:

P is the position of the kite. Its height from the point Q (on the ground)=PQ=60m

Let OP=l be the length of the string

∠POQ=60

o

(given)

sin(Θ)=

Hypotenuse

Opposite

Now,

OP

PQ

=sin60

o

⇒

l

60

=sin60

o

=

2

3

⇒

l

60

=

2

3

⇒ l=

3

3×2×20

m

⇒ l=40

3

m

The length of the string is 40
