In a right angled triangle ABC, right angled at B, given 15 cos A - 8 Sin A = 0,1. Sin A + Cos A / 2 Cos A - Sin A = ? 2. 15 cot A + 17 sin A / 2 Cos A - Sin A = ?It will be useful if you guys explain me with steps Thank you !!Have a nice day po !!✌​

Answer»

Step-by-step explanation:

Given:-

In a right angled triangle ABC, right angled at B, given 15 cos A - 8 Sin A = 0.

To find:-

Find the following:

1. Sin A + Cos A / 2 Cos A - Sin A = ?

2. 15 cot A + 17 sin A / 2 Cos A - Sin A = ?

Solution:-

Given that

15 cos A - 8 Sin A = 0

=> 15 Cos A = 8 Sin A

=> Cos A / Sin A = 8/15

=> Cot A = 8/15-------(1)

On SQUARING both sides

=> Cot^2 A = (8/15)^2

=> Cot^2 A = 64/225

Now

=> 1+Cot^2 A = 1+(64/225)

=> 1+ Cot^2 A = (225+64)/225

=> 1+Cot^2 A = 289/225

We know that

Cosec^2 A - Cot^2 A = 1

=> Cosec^2 A = 1+Cot^2 A

=> Cosec^2 A = 289/225

=> Cosec A = √(289/225)

=> Cosec A = 17/15

Sin A = 15/17---------(2)

On squaring both sides

=> Sin^2 A = 225/289

=> 1- Sin^2 A = 1-(225/289)

=> 1-Sin^2 A = (289-225)/289

=> 1- Sin^2 A = 64/289

We know that

Sin^2 A + Cos^2 A = 1

=> Cos^2 A = 64/289

=> Cos A =√(64/289)

Cos A = 8/17-----------(3)

I) The value of

(Sin A + Cos A) / (2 Cos A - Sin A )

=>[ (15/17)+(8/17)]/[2(8/17)-(15/17)]

=>[ (15+8)/17 ]/ [ (16-15)/17]

=> (23/17)/(1/17)

=> 23/1

=>23

(Sin A + Cos A) / (2 Cos A - Sin A ) = 23

2) The value of

(15 cot A + 17 sin A) / (2 Cos A - Sin A)

=> [15(8/15)+17(15/17)] /[ 2(8/17)-(15/17)]

=> [(15×8/15)+(17×15/17)] / [(2×8/17)-(15/17)]

=> (8+15)/ [(16/17)-(15/17)]

=> 23/[(16-15)/17]

=> 23/(1/17)

=> 23×(17/1)

=> 23×17

=> 391

(15 cot A + 17 sin A) / (2 Cos A - Sin A) = 391

Answer:-

The values of

i)(Sin A + Cos A) / (2 Cos A - Sin A ) = 23

ii)(15 cot A + 17 sin A) / (2 Cos A - Sin A) = 391

Used formulae:-

  • Cosec^2 A - Cot^2 A = 1

  • Sin^2 A + Cos^2 A = 1

  • Cot A = Cos A / Sin A

  • Cosec A = 1/ Sin A

The traingle with sides 25cm 5cm n 24 cm is a right traingle​

Answer»

Step-by-step explanation:

ACCORDING to the Pythagoras theorem, in a right-angle triangle the SUM of square of two sides must be equal to square of third side. But Given sides do not make a right triangle because it does not satisfy the property of Pythagoras theorem so the triangle with sides 25cm, 5CM and 24cm is not a right triangle

अगर 40% अधिक मजदूर काम पर लगाए गए और उनकी कार्यक्षमता भी पहले की तुलना में 25% अधिक हो तो एक कार्य को पूरा होने में लगने वाले समय में % बदलाव ज्ञात करें? (a) 30% (b) 33% (c) 33.33% (d) 37.5%​

Answer»

प्रश्न :- अगर 40% अधिक मजदूर काम पर लगाए गए और उनकी कार्यक्षमता भी पहले की तुलना में 25% अधिक हो तो एक कार्य को पूरा होने में लगने वाले समय में % बदलाव ज्ञात करें ?

(a) 30%

(b) 33%

(c) 33.33%

(d) 37.5%

उतर :-

माना पहले मजदूर = 100

→ अब, बढ़ गए = 40% = 40 मजदूर,

→ कार्यक्षमता पहले की तुलना में बड़ी = 25% = (25/100) = (1/5)

अत,

→ मजदूर बढ़े = (1/5) * 40 = 8 मजदूर L

इसलिए,

→ कुल मजदूर = 40 + 8 = 48 मजदूर

अत,

→ अनुपात समय का = 100 : 148

→ समय में बदलाव = (48 * 100) / 148 ≈ 33% (B) (ANS.)

The speed of the motorboat in still water if a motorboat travels 30 minutes upstream against 4mphcurrent. Returning with the current takes 18 minutes.a)14 mphb) 15 mphc)16 mphd)17 mph​

Answer»

Answer:

LET, speed of motorboat in still water is k mph

Then for upstream rate is (k-4) mph & for returning rate is (k+4) mph.

So, for going in 30 minutes it goes 30(k-4)/60 mile = (k-4)/2 mile

For returning in 18 minutes it goes 18(k+4)/60 mile = 3(k+4)/10 mile

Accordingly , (k-4)/2 = 3(k+4)/10

Or, 10K - 40 = 6k + 24

Or, 4k = 64

Or, k = 16

So, speed of motorboat in still water is 16 mph.

So, rate in upstream is 12 mph and downstream is 20 mph.

Upstream take 30 minutes and downstream takes 18 minutes

Both cover the distance 6 mile. ( By putting k VALUE in upstreams and downstream goes distance).

If absolute error is 1V and % error is 1.25% then Relative accuracy is_________

Answer»

Given :- ∂A = 1 , εA = 1.25%

To find :- relative accuracy

Solution :-

  • here we have to find limits of VALUE

  • A = ∂A ÷ εA × 100
  • A = 1 ÷ 1.25 × 100
  • A = 80
  • So ORIGINAL value is A= 80
  • Limits of value = A ± ∂A
  • = 80 ± 1
  • = 79 , 81

So accuracy is 79 , 81
