प्रश्न
In ∆ABC, points P and Q are on CA and CB, respectively such that CA = 16 cm, CP = 10 cm, CB = 30 cm and CQ = 25 cm. Is PQ || AB?
उत्तर
Given: `AC=16cm,CP=10cm,CB=30cm` and `CQ=25cm`, we get
We will check whether `(CP)/(AC)=(CQ)/(BC)` or not to conclude whether `PQ||AB`.
`(CP)/(AC)=(10cm)/(16cm)=5/8`
`(CQ)/(CB)=(25cm)/(30cm)=5/6`
`∴ (CP)/(AC)≠ (CQ)/(CB)`
Hence, PQ is not parallel to AB.

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8 m above the surface of the water and the fly at the end of the string rests on the water 3.6 m away and 2.4 m from a point directly under the tip of the road. Assuming that her string (from the tip of her road to the fly) is taut, how much string does she have out (in the given figure)? If she pulls the string at the rate of 5 cm per second, what will the horizontal distance of the fly from her after 12 seconds.
