Question

A little boy is flying a kite. The string of the kite makes an angle of 30 o with the ground. If the
height of the kite is h = 9 m, find the length (in meters) of the string that the boy has used.

Answer 1

Answer:

18m

Step-by-step explanation:

Sin 30 degrees = perpendicular/hypotenuse (here the string is the hypotenuse)

1/2 = height/length

Length/2=height

Length=height x 2

Length=9 x 2

Length = 18m
