BRAINIEST QUESTION♥️♥️♥️•nazima is fly fishing in a stream.the tip of her fishing rod is 1.8m above the surface of the water and the fly at the end of the string rests on the water 3.6m away and 2.4m from a point directly under the tip of the rod assuming that her string is taut,how much string does she have out?if she pulls in the string at rate of 5cm per second, what will be the horizontal distance of the fly from her after 12 seconds?MOST BRAINIEST QUESTION!!!!TRY IF YOU CAN ANS RIGHTLY.NO SPAM ❎❎GOOD LUCK BEST ANSWER WILL BE MARKED AS BRAINIEST 30 POINTS.

Answer:
Ans. I. To find The length of AC.
By Pythagoras theorem,
AC2 = (2.4)2 + (1.8)2
AC2 = 5.76 + 3.24 = 9.00
AC = 3 m
Length of string she has out= 3 m
Length of the string pulled at the rate of 5 cm/sec in 12 seconds
= (5 x 12) cm = 60 cm = 0.60 m
Remaining string left out = 3 – 0.6 = 2.4 m
II. To find: The length of PB
PB2 = PC2 – BC2
= (2.4)2 – (1.8)2
= 5.76 – 3.24 = 2.52
PB = = 1.59 (approx.)
Hence, the horizontal distance of the fly from Nazima after 12 seconds
= 1.59 + 1.2 = 2.79 m (approx.)
