Difference of squares of two numbers is 200 and six times The square of one number Is equal To tenTimes The larger number . Then the larger number is

Answer»

ong>Given : Difference of SQUARES of two NUMBERS is 200 and six times The square of one number Is equal To TENTIMES The larger number

To Find : the larger number

SOLUTION:

LET say smaller number = S

Larger number = L

Difference of squares of two numbers is 200

=> L² - S² = 200

The square of one number Is equal To ten Times The larger number .

=> 6S² = 10L

=> S² = 10L/6

=> S² = 5L/3

L² - S² = 200

=> L² - 5L/3 = 200

=> 3L² - 45L + 40L -  600 = 0

=> 3L(L - 15) + 40(L - 15)  = 0

=> (L - 15)(3L + 40) = 0

L = 15

Larger Number is 15

parallel sides of trapeziumm is 7 cm and 13 cm and each is non parallel side is 5cm long .Find the area of trapezium​

Answer»

ong>Answer:

SOLUTION

Let PQRS be the given trapezium

in which PQ ║ SR.

                                                   

Draw RX ⊥ PQ and RY ║ SP,

these meeting PQ at X and Y.

                                                   

It is clear that PYRS is a

parallelogram.

                                                   

∴ PY = SR = 13 cm

 YQ = PQ - PY = 25 cm - 13 cm

       = 12 cm

                                                   

Now, RY = SP = 10 cm and RQ = 10 cm

                                                   

∴ ΔRYQ  is an ISOSCELES triangle and

RX ⊥ YQ.

                                                   

Clearly, X is the midpoint of YQ.

∴ XY = XQ = 1/2 × YQ = 1/2 × 12 CM = 6 CM

                                                   

In ΔRXY, we have

(RX)² = (RY)² - (XY)² (Here we use Pythagoras theorem)

        = (10)² - (6)²

        = 100 - 36

        = 64

⇒ RX = 8 cm

                                                   

Area of the trapezium PQRS

= 1/2 × (25+13) × 8

= 152 cm²

Given a=2 ,d=8, Sn=90, find a= ? and A9​

Answer» ONG>Step-by-step explanation:

Here,

Given :

a = 2

d = 8

sn = 90

So,

According to formula ,

Sn = a + ( 2d - a)d = A9

90 = 2 + ( 16 - 2) 8

90 = 2 + 128 - 16

90 = 130 -16

90A9= 114

A9 = 114/90

✓sin²+cosec² = tan+cot​

Answer»

ong>Answer:

SOHCAHTOA

Sin θ = Opposite side / HYPOTENUSE side

Cos θ = ADJACENT side / Hypotenuse side

Tan θ = Opposite side / Adjacent side

Csc θ = Hypotenuse side / Opposite side

Sec θ = Hypotenuse side / Adjacent side

Cot θ = Adjacent side / Opposite side

Reciprocal Trigonometric Identities

Sinθ = 1 / Cosecθ

Cscθ = 1 / Sinθ

Cosθ = 1 / Secθ

Secθ = 1 / Cosθ

Tanθ = 1 / Cotθ

Cotθ = 1 / Tanθ

Other Trigonometric Identities

Sin²θ + Cos²θ = 1

Sin²θ = 1 - Cos²θ

Cos²θ = 1 - Sin²θ

Sec²θ - Tan²θ = 1

Sec²θ = 1 + Tan²θ

Tan²θ = Sec²θ - 1

Csc²θ - Cot²θ = 1

Csc²θ = 1 + Cot²θ

Cot²θ = Csc²θ - 1

Double Angle Identities

Sin2A = 2 ⋅ SinA ⋅ CosA

Cos2A = Cos²A - Sin²A

Tan2A = 2 ⋅ TanA / (1 - Tan²A)

Cos2A = 1 - 2 ⋅ Sin²A

Cos2A = 2 ⋅ Cos²A - 1

Sin2A = 2 ⋅ TanA / (1 + Tan²A)

Cos2A = (1 - Tan²A) / (1 + Tan²A)

Sin²A = (1 - Cos2A) / 2

Cos²A = (1 + Cos2A) / 2

Half Angle Identities

SinA = 2 ⋅ Sin(A/2) ⋅ Cos(A/2)

CosA = Cos²(A/2) - Sin²(A/2)

TanA = 2 ⋅ Tan(A/2) / [1 - Tan²(A/2)]

CosA = 1 - 2 ⋅ Sin²(A/2)

CosA = 2 ⋅ Cos²(A/2) - 1

SinA = 2 ⋅ Tan(A/2) / [1 + Tan²(A/2)]

CosA = [1 - Tan²(A/2)] / [1 + Tan²(A/2)]

Sin²A/2 = (1 - Cos A) / 2

Cos²A/2 = (1 + Cos A) / 2

Tan²(A/2) = (1 - CosA) / (1 + CosA)

Compound Angles Identities

Sin(A + B) = SinA ⋅ CosB + CosA ⋅ SinB

Sin(A + B) = SinA ⋅ CosB + CosA ⋅ SinB

Cos(A + B) = CosA ⋅ CosB - SinA ⋅ SinB

Cos(A - B) = CosA ⋅ CosB + SinA ⋅ SinB

Tan(A + B) = [TanA + TanB] / [1- TanA ⋅ TanB]

Tan(A - B) = [TanA - TanB] / [1 + TanA ⋅ TanB]

Sum to PRODUCT Identities

SinC + SinD = 2 ⋅ Sin[(C+D) / 2] ⋅ cos [(C-D) / 2]

SinC - SinD = 2 ⋅ Cos [(C+D) / 2] ⋅ Sin [(C-D) / 2]

Please do this, rationalise the denominator , I will mark brainliest plz urgently.​

Answer»

ong>Step-by-step EXPLANATION:

Answer :

Now,

y = {√(a + X) + √(a - x)}/{√(a + x) - √(a - x)}

We RATIONALISE the denominator by multiplying both the numerator and the denominator by {√(a + x) + √(a - x)}

So,

y = {√(a + x) + √(a - x)}{√(a + x) + √(a - x)}/{√(a + x) - √(a - x)}/{√(a + x) + √(a - x)}

= {a + x + 2√(a² - x²) + a - x}/(a + x - a + x)

= {2a + 2√(a² - x²)}/(2x)

XY = a + √(a² - x²)

⇒ xy - a = √(a² - x²)

Now, squaring both sides, we get

(xy - a)² = a² - x²

⇒ x²y² - 2axy + a² = a² - x²

⇒ xy² - 2ay = - x

⇒ xy² - 2ay + x = 0
