Question

5) A kite is flying at a height of 60 m from the ground. The string
makes an angle 30' from the horizontal ground. Find the length of
the string.​

Answer 1

Answer:

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
