2.	Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8m above thesurfaceof 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 rod. Assuming that her string (fromthe tip of her rod to the fly) is taut, how much string does she have out (SeeFig. 7.235)? If she pulls the string at the rate of 5 cm per second, what will thehorizontal distance of the fly from her after 12 seconds .
Answer» ong>Answer: 2.79m Step-by-step explanation: Let AB be the height of the tip of the fishing rod from the water surface. Let BC be the HORIZONTAL distance of the fly from the tip of the fishing rod. Then, AC is the length of the string. ∴ AC 2 =AB 2 +BC 2 [ By Pythagoras theorem ] ∴ AC 2 =(1.8) 2 +(2.4) 2 ∴ AC 2 =3.24+5.76 ∴ AC 2 =9 ∴ AC=3m Thus, the length of the string out is 3m She pulls the string at the RATE of 5cm/s ∴ String PULLED in 12 second = 12×5=60cm=0.6m Let the fly be at point D after 12 seconds. Length of string out after 12 second is AD. ⇒ AD = AC - String pulled by Nazima in 12 seconds. ⇒ AD=(3−0.6)m=2.4m ⇒ In △ADB, AB 2 +BD 2 =AD 2 (1.8) 2 +BD 2 =(2.4) 2 BD 2 =5.76−3.24 BD 2 =2.52 ∴ BD=1.587m Horizontal distance of fly =BD+1.2m Horizontal distance of fly =1.587m+1.2m ∴ Horizontal distance of fly =2.79m I hope you understand my so please please please please please please please please please please please please please please please please please please please please please please please please MARK me as brainlest

Nazima is fly fishing in a stream. The tip of her fishing rod is 1.8m above thesurfaceof 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 rod. Assuming that her string (fromthe tip of her rod to the fly) is taut, how much string does she have out (SeeFig. 7.235)? If she pulls the string at the rate of 5 cm per second, what will thehorizontal distance of the fly from her after 12 seconds .

Answer»

ong>Answer:

2.79m

Step-by-step explanation:

Let AB be the height of the tip of the fishing rod from the water surface.

Let BC be the HORIZONTAL distance of the fly from the tip of the fishing rod.

Then, AC is the length of the string.

∴ AC

2

=AB

2

+BC

2

[ By Pythagoras theorem ]

∴ AC

2

=(1.8)

2

+(2.4)

2

∴ AC

2

=3.24+5.76

∴ AC

2

=9

∴ AC=3m

Thus, the length of the string out is 3m

She pulls the string at the RATE of 5cm/s

∴ String PULLED in 12 second = 12×5=60cm=0.6m

Let the fly be at point D after 12 seconds.

Length of string out after 12 second is AD.

⇒ AD = AC - String pulled by Nazima in 12 seconds.

⇒ AD=(3−0.6)m=2.4m

⇒ In △ADB,

AB

2

+BD

2

=AD

2

(1.8)

2

+BD

2

=(2.4)

2

BD

2

=5.76−3.24

BD

2

=2.52

∴ BD=1.587m

Horizontal distance of fly =BD+1.2m

Horizontal distance of fly =1.587m+1.2m

∴ Horizontal distance of fly =2.79m

I hope you understand my

5.	SIDES AB,BC AND CA OF ΔABC touches a circle at F,D and E.Prove that AF +BD+CE=1/2*perimeter of ΔABC
Answer» ong>Step-by-step explanation: Since, LENGTHS of the tangents drawn from an EXTERIOR point to a circle are equal. ∴ AF = AE …….(i) BD = BF ………(ii) And CE = CD ……….(iii) ADDING (i), (ii) and (iii), we get AF + BD + CE = AE + BF + CD Now, Perimeter of △ABC = AB + BC + AC = (AF + FB) + (BD + CD) + (AE + EC) = (AF + AE) + (BF + BD) + (CD + CE) = 2AF + 2BD + 2CE = 2(AF + BD + CE) [From (i), (ii) and (iii), we get AE = AF, BD = BF and CD = CE] ∴ AF + BD + CE = ½ (Perimeter of △ABC) HENCE, AF + BD + CE = AE + BF + CD = ½(Perimeter of △ABC) Hence proved.

SIDES AB,BC AND CA OF ΔABC touches a circle at F,D and E.Prove that AF +BD+CE=1/2*perimeter of ΔABC

Answer»

ong>Step-by-step explanation:

Since, LENGTHS of the tangents drawn from an EXTERIOR point to a circle are equal.

∴ AF = AE …….(i)

BD = BF ………(ii)

And CE = CD ……….(iii)

ADDING (i), (ii) and (iii), we get

AF + BD + CE = AE + BF + CD

Now, Perimeter of

△ABC = AB + BC + AC

= (AF + FB) + (BD + CD) + (AE + EC)

= (AF + AE) + (BF + BD) + (CD + CE)

= 2AF + 2BD + 2CE

= 2(AF + BD + CE) [From (i), (ii) and (iii), we get

AE = AF, BD = BF and CD = CE]

∴ AF + BD + CE = ½ (Perimeter of △ABC)

HENCE, AF + BD + CE = AE + BF + CD = ½(Perimeter of △ABC)

Hence proved.
