Question

A kite is flying at a height of 80m above the ground andthe string attached to it is tied to a point on the ground . The inclination of string with ground is 60degree.Assuming that there is no slack in string .Find the lenght of string

Answer 1

Hey mate ..!!
watch out the attachment...

I hope it helps....

Answer 2

Answer:

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
