MCQ - 391-9123

Question:

A kite is flowing at a height of 75 cm from the level ground, attached to a string inclined at 60˚ to the horizontal. The length of string with no slack in it, is

  1. 50√ 2 m
  2. 25√ 3 m
  3. 50√ 3 m
  4. 25√ 3 m

Correct Answer: C

Explanation:

Consider, the situation in the form of a triangle ABC where A is the kite and AC shows the height of kite i.e.
AC = 75 cm
And
AB be the string with angle of inclination i.e.
∠CAB = θ = 60°
We have to find length of string i.e. AB
Clearly, ABC is a right – angled triangle
So, we have

12 -53880156
On cross multiplying we get,
13 -25907066
On rationalizing we get
14 -89082520
