Question

A kite is flying at a height of 60 m from the level surface attached to a string inclined at 30° to the horizontal. Then the length of the string in metres is

Answer 1

Answer:

120 m

Step-by-step explanation:

Let s be the length of the string.

Then

sin 30° = opp / hyp = height / string = 60 m / s

=>  s = 60 m / sin 30° = 60 m / 0.5 = 120 m

Answer 2

sin30•=AB/AC
1/2=60/AC
AC=120
