5.	Two angles are supplementary and one angle is 18* greater than the other. Find the measure of each angle
Answer» ★Given : TWO ANGLES are supplementary. One angle is 18° greater than the other. ★To FIND : Measure of each angle. ★Solution : LET the measure of one angle is 'x'. As one angle is 18° greater than the other, The measure of another angle is x+18. Given that the two angles are supplementary. Hence they add upto 180°.That is, →x+x+18=180 →2x + 18 = 180 →2x = 162 →x = 162/2 →x=81° Therefore, Measure of another angle: →x + 18 →81 + 18 →99° Hence,the angles are 81° & 99°. ______________

Two angles are supplementary and one angle is 18* greater than the other. Find the measure of each angle

Answer»

★Given :

TWO ANGLES are supplementary.
One angle is 18° greater than the other.

★To FIND :

Measure of each angle.

★Solution :

LET the measure of one angle is 'x'.

As one angle is 18° greater than the other,

The measure of another angle is x+18.

Given that the two angles are supplementary.

Hence they add upto 180°.That is,

→x+x+18=180

→2x + 18 = 180

→2x = 162

→x = 162/2

→x=81°

Therefore,

Measure of another angle:

→x + 18

→81 + 18

→99°

Hence,the angles are 81° & 99°.

6.

Divide 240 into two parts such that one third of one part may be less than the by 72

Answer»

Answer:

Let the first part be a

Second part = 240 - a

According to question,

a/3 + 72 = 240 - a

=> a/3 + a = 240 - 72

=> 4a/3 = 168

=> a = 168 × 3 /4

=> a = 42 × 3

=> a = 126

First part = 126

Second part = 240 - a

= 240 - 126

= 114

Answer» ★Given : Rajesh weight is 5 kg more than rams weight. NEHA weight is 3 kg more than rams weight. The weight of all 3 is 103 kg. ★To find : Weight of Ram. ★Solution : Let, Rajesh's weight = x Ram's weight = y Neha's weight = Z Given that weight of rajesh is 5kg more than weight of rams.Therefore, →x + 5 = y →x = y-5 Also given that weight of Neha is 3kg more than Rams.Therefore, →z = y + 3 Sum of all three is 103 kg. That is, sum of weight of rajesh,neha & rams is 103. ∴x + y + z = 103 Putting values, →y-5 + y + y+3 = 103 →3y - 2 = 103 →3y = 103 + 2 →3y = 105 →y = 35 kg Therefore,the weight of rams is 35kg. __________

Rajesh weight is 5 kg live than rams weight and Neha weight is 3 kg more than rams weight if the weight of 3 is 103 kg then the weight of rams

Answer»

★Given :

Rajesh weight is 5 kg more than rams weight.
NEHA weight is 3 kg more than rams weight.
The weight of all 3 is 103 kg.

★To find :

Weight of Ram.

★Solution :

Let,

Rajesh's weight = x
Ram's weight = y
Neha's weight = Z

Given that weight of rajesh is 5kg more than weight of rams.Therefore,

→x + 5 = y

→x = y-5

Also given that weight of Neha is 3kg more than Rams.Therefore,

→z = y + 3

Sum of all three is 103 kg.

That is, sum of weight of rajesh,neha & rams is 103.

∴x + y + z = 103

Putting values,

→y-5 + y + y+3 = 103

→3y - 2 = 103

→3y = 103 + 2

→3y = 105

→y = 35 kg

Therefore,the weight of rams is 35kg.

Answer» EXPLANATION. ⇒ 1/(X - 1)(x - 2) + 1/(x - 2)(x - 4) + 1/(x - 3)(x - 4) = 1/6. Taking L.C.M in this equation, we get. ⇒ (x - 3)(x - 4) + (x - 1)(x - 4) + (x - 1)(x - 2)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)(x - 4) + (x - 1)[(x - 4) + (x - 2)]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)(x - 4) + (x - 1)[x - 4 + x - 2]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)(x - 4) + (x - 1)(2x - 6)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)(x - 4) + (x - 1)2(x - 3)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)[(x - 4) + 2(x - 1)]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)[x - 4 + 2x - 2]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)(3X - 6)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ (x - 3)3(x - 2)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6. ⇒ 3/(x - 1)(x - 4) = 1/6. ⇒ (x - 1)(x - 4) = 18. ⇒ x² - 4x - x + 4 = 18. ⇒ x² - 5x + 4 = 18. ⇒ x² - 5x - 14 = 0. Factorizes the equation into middle term split, we get. ⇒ x² - 7x + 2x - 14 = 0. ⇒ x(x - 7) + 2( x - 7) = 0. ⇒ (x + 2)(x - 7) = 0. ⇒ x = -2 & x = 7.

1) 1/(x - 1)(x - 2) + 1/(x - 2)(x - 4) + 1/(x - 3)(x - 4) = 1/6 where, x not equal to 1,2,3,4.Please don't Spam

Answer»

EXPLANATION.

⇒ 1/(X - 1)(x - 2) + 1/(x - 2)(x - 4) + 1/(x - 3)(x - 4) = 1/6.

Taking L.C.M in this equation, we get.

⇒ (x - 3)(x - 4) + (x - 1)(x - 4) + (x - 1)(x - 2)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)(x - 4) + (x - 1)[(x - 4) + (x - 2)]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)(x - 4) + (x - 1)[x - 4 + x - 2]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)(x - 4) + (x - 1)(2x - 6)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)(x - 4) + (x - 1)2(x - 3)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)[(x - 4) + 2(x - 1)]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)[x - 4 + 2x - 2]/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)(3X - 6)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ (x - 3)3(x - 2)/(x - 1)(x - 2)(x - 3)(x - 4) = 1/6.

⇒ 3/(x - 1)(x - 4) = 1/6.

⇒ (x - 1)(x - 4) = 18.

⇒ x² - 4x - x + 4 = 18.

⇒ x² - 5x + 4 = 18.

⇒ x² - 5x - 14 = 0.

Factorizes the equation into middle term split, we get.

⇒ x² - 7x + 2x - 14 = 0.

⇒ x(x - 7) + 2( x - 7) = 0.

⇒ (x + 2)(x - 7) = 0.

⇒ x = -2 & x = 7.

Answer» Answer: Perimeter given = 20 cm Breadth Given = 4 cm LENGTH given = let’s consider it as variable x 2( length + breadth ) = perimeter of rectangle 2( x + 4 ) = 20 cm 2X + 8. = 20 cm 2x = 20 - 8 (transposition) 2x = 12 cm 2x/2 = 12/2 x = 6 cm (breadth) Therefore length = 4CM and breadth = 6 cm Hence area of rectangle = length x breadth (A) = 4 x 6 (A) = 24 cm Therefore breadth = 6cm; Area = 24 cm Step-by-step explanation: Hope it helps you pls mark as brainliest.

41.

The rectangle is greater than its breadth by 4cm and it's perimeter is 20cm the length and breadth are_

Answer»

Answer:

Perimeter given = 20 cm

Breadth Given = 4 cm

LENGTH given = let’s consider it as variable x

2( length + breadth ) = perimeter of rectangle

2( x + 4 ) = 20 cm

2X + 8. = 20 cm

2x = 20 - 8 (transposition)

2x = 12 cm

2x/2 = 12/2

x = 6 cm (breadth)

Therefore length = 4CM and breadth = 6 cm

Hence area of rectangle = length x breadth

(A) = 4 x 6

(A) = 24 cm

Therefore breadth = 6cm; Area = 24 cm

Step-by-step explanation:

Hope it helps you pls mark as brainliest.

AB and BC form a right angle at point B. If A = (-3, -1) and B = (4, 4), what is the equation of BC?A. x + 3y = 16B. 2x + y = 12C. -7x − 5y = -48D. 7x − 5y = 48

Answer»

Step-by-step explanation:

A(-3,-1)

B(4,4)

m(AB)=y2-y1/x2-x1

=4+1/4+3

=5/7

m(AB)*m(BC)= -1

m(BC)= -7/5

Equation of BC

y-y1=m(x-x1)

y-4= -7/5(x-4)

5y-20= -7x+28

5y+7x-48=0
