A boy flying a kite holds the string of length 24.4 m such that it makes an angle of 30° with the ground. Find the height of the kite from the ground.

Correct option is C

Given
Length of the string (Hypotenuse) = 24.4 m
Angle with the ground $$(\theta)$$​= 30°
Formula Used
​$$\sin(\theta) = \frac{Height}{Hypotenuse}$$​​
Solution
​$$\sin(30°) = \frac{Height}{24.4} \\\ \\Since \sin(30°) = \frac{1}{2}\\\ \\\frac{1}{2} = \frac{Height}{24.4} \\\ \\Height = \frac{24.4}{2} = 12.2 m\\$$​​
Final Answer
So the correct answer is (c)
