If 4 tanQ=3 then find the value of 4sinQ-cosQ/4sinQ+cosQ​

Answer»

4tanθ = 3 so,

tanθ = 3/4

Now, (4sinθ - cosθ)/(4sinθ + cosθ)

First of all DIVIDE cosθ with both LHS and RHS , (4sinθ/cosθ - cosθ/cosθ)/(4sinθ/cosθ + cosθ/cosθ) = (4tanθ - 1)/(4tanθ + 1)

Now, put tanθ = 3/4 = (4 × 3/4 - 1)/(4 × 3/4 + 1)

= (3 - 1)/(3 + 1) = 2/4 = 1/2

SinA+ cos A=√2sinA then,sinA-cosA=

Answer»

Given :

To find :

  • Sin A - cos A

Solution :

Sin A + Cos A = √2 sin A

  • Squaring both the sides :

(sin A + cos A)² = (√2 sin A)²

  • Solving by using Identity :
  • ( x + y)² = x² + y² + 2xy

Sin² A + Cos² A + 2SIN A Cos A = 2 sin²A ____(1)

Using Identity

Sin² A + cos ² A = 1

Sin² A = 1 - cos² A ______(2)

Using equation 2 JININ n equation 1 :

1 - cos² A + cos² A + 2 sin A cos A = 2 ( 1 - cos²A)

1 + 2 sin A cos A = 2 - 2 cos² A

2 sin A cos A =  2 - 1 - 2 cos² A

2 sin A cos A = 1  - 2cos² A

2cos² A = 1 - 2 sin A cos A

2Cos² A =  sin² A + cos² A - 2 sin A cos A

Now , Using identity

( x - y)² = x² + y² - 2xy

2Cos² A = ( sin A - cos A)²

Sin A - cos A = √(2 cos² A)

Sin A - cos A = ± √2 cos A

Three numbers are in the ratio of 345and three cm is 2400 . There HCF is?

Answer»

ANSWER:

Three number are in the ratio of 3 : 4 : 5 and their L.C.M. is 2400. Their H.C.F. is:

A) 40

B) 80

C) 120

D) 200

Answer: A) 40

Explanation:

Let the numbers be 3X, 4x and 5x.

Then, their L.C.M. = 60x.

So, 60x = 2400 or x = 40.

The numbers are (3 x 40), (4 x 40) and (5 x 40).

Hence, REQUIRED H.C.F. = 40.

Find zeroes of the polynomial f(x)=X2 - 121and verify the relationship between the zeroes and its coefficients

Answer»

Step-by-step EXPLANATION:

We have polynomial t² - 121.

The ZEROES and verify the relationship between the zeroes and coefficient.

p(X) = t² - 121

Zero of the polynomial is p(x) = 0

So;

∴ The α = 11 and β = -11 are the zeroes of the polynomial.

As the given quadratic polynomial as we compared with ax² + bx + c

a= 1

b = 0

c = -121

Now;

The angles of a quadrilateral are in AP with d = 10, find the angles.​

Answer»

Answer:

given= 10°

let us TAKE ANGLES as a-d , a , a+d , a+2d

now we know that sum of all quadrilateral is 360°

so we get

a-d + a + a+d + a+2d= 360°

4a+ 2(10) = 360°

a= 85°

first angle = a-d = 85 - 10= 75°

second angle a= 85°, third angle = a+2d= 85+ 2(10)= 85+20= 105°

fourth angle = a+d = 85+ 10= 95°

Answer»

Answer:

Step-by-step explanation:GIVEN a+B should be EQUAL to -3

i)take b as 0(b=0)

so, a+0=-3

a=-3

(-3,0)

ii)take a as 0(a=0)

so,0+b=-3

b=-3

(0,-3)

(iii)take a as 1(a=1)

so,1+b=-3

b=-3-1

b=-4
