• # question_answer Direction: Q. 21 to 25 Nazima is fly fishing in a stream. The tip of her fishing rod is $\text{1}.\text{8 m}$ above the surface of the water and the fly at the end of the string rests on the water $3.6\text{ m}$away and $2.4\text{ m}$ from a point directly under the tip of the rod. Assuming that her string (from the tip of her rod to the fly) is taut, answer the following questions given below: How much string does she have out? A) $1\,m$ B) $1.5\,m$ C) $2.5\,m$ D) $3\,m$

 Length of the string that she has out $=\sqrt{{{(1.8)}^{2}}+{{(2.4)}^{2}}}$ (Using Pythagoras theorem) $=\sqrt{3.24+5.76}=3m$ $\therefore$  She has 3 m string out. So, option [d] is correct.
