Given -- ΔABC other than equilateral triangle.

The construction is already given in the picture.So let me just establish the relation between the sides.
Let  AB = AD = DB

ABD is an equilateral triangle since AB = AD = DB

∠ABD = ∠ADB = ∠BAD = 60°

Longest side= BC
Angle opposite to longest side = ∠BAC

Here it is clear that ∠BAC = ∠BAD + ∠CAD
So ∠BAC > ∠BAD
∠BAC > 60°

2/3 of right angle = 2/3 × 90 = 60

SO,
angle(BAC) > 2/3 of right angle

Let the common multiple of each term of ratio be x.

Then, ratio becomes  2x:7x

As , their sum should be 180°,

⇒2x + 7x = 180°

⇒9x = 180°

⇒x = 180 ÷ 9

⇒x = 20

So, the angles are ,

2x = 2 * x = 2*20 = 40°

7x = 7 * x = 7 * 20 = 140°

We can verify by adding them , as 140+40 = 180°

Answer : hence, the angles are 40° and 140°.

There can be infinitely many rational numbers between 3 and 4.



Thus, six ratonal numbers between 3 and 4 are   .

OR



Thus, six rational numbers between 3 and 4 can be taken as

A rational number between 3 and 4 is 1/2 (3 + 4) = 7/2.

Then, 3 < 7/2 < 4

A rational number between 3 and 7/2 = 1/2 {3 + 7/2} = 1/2 (3/1 + 7/2)

= 1/2 ((6 + 7)/2) = (1/2 × 13/2) = 13/4

A rational number between 7/2 and 4 = 1/2 {7/2 + 4} = 1/2 (7/2 + 4/1)

= 1/2 ((7 + 8)/2) = {1/2 × 15/2} = 15/4

Therefore, 3 < 13/4 < 7/2 < 15/4 < 4

Hence, 13/4, 7/2 and 15/4 are the three rational numbers lying between 3 and 4.

let x=0.47. 【bar on 7】
=>x=0.4777

[Since only one digit is repeating, so multiply x with 10.]

•°• 10x=10×0.4777...

=>10x=4.777

=>10x=4.3+0.4777

=>10x=4.3+x

[since x =0.4777]

=>10x-x=4.3

=>9x=4.3

=>x=4.3/9

=>x=43/9

In mathematics, factor theorem is used as a linking factor and zeros of the polynomial.

If f(x) is a polynomial of degree n ≥ 1 and ‘a’ is any real number, then

  • (x-a) is a factor of f(x), if f(a)=0
  • Its converse “ if (x-a) is a factor of the polynomial f(x), then f(a)=0”

Factor theorem is commonly used for factoring a polynomial and finding the roots of the polynomial equation. It is a special case of a polynomial remainder theorem.

p(x)=3x³+4x²-5x+8

x = -2

p(-2) = 3(-2)³ + 4(-2)² - 5(-2) + 8

 

p(-2) = 3(-8) + 4(4) +10 + 8

 

p(-2) = -24 + 16 +10 + 8

 

p(-2) = -24 + 34

 

p(-2) = 10

                We have 99 = 100 – 1

                ∴ 993 = (100 – 1)3

                = 1003 – 13 – 3(100)(1)(100 – 1)

                = 1000000 – 1 – 30000 + 300

                = 100300 – 30001
