Applications of Trigonometry Heights and Distances Chapter 9 Exercise 9.1 Question 5
5. A kite is flying at a height of 60 m above the ground. The string attached to the kite is temporarily tied to a point on the ground. The inclination of the string with the ground is
. Find the length of the string, assuming that there is no slack in the string.
Solution:
It is given that kite is flying at the height of 60 m. It means we have AB = 60 m
The string is tied to a point on the ground and we want to find length of string which is AC.
We have
m
Therefore, the length of string AC =
m
