Question

A kite is flying with a thread 150m long .if the thread is assumed stretched straight and makes an angle of 60degree with horizontal , find the height of the kite above the ground.(Take square root=1.73

Answer 1

Answer:

Step-by-step explanation:

           /lC   kite

        /   l

     /      l   height of the kite from the ground

  /         l

/.60....... l

A            B

AC=150m

∠CAB=60°

we know sin 60°=perpendicular/hypotenuse

sin60°=BC/AC

√3/2=BC/150

BC=150√3/2=75√3

BC=75×1.73=129.75 m

Answer 2

Answer:

129.75

Step-by-step explanation:

length above ground = ab

given ac = 150

60 = sin60 because hypot is given and we have to find perpendicular

so, sin 60 = P/H = P/150

1.73/2 = P / 150

by cross multiplying

we get 259.50/2=P

so, answer is 129.75
