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°.

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

(99)3
We have 99 = 100 – 1
∴ 993 = (100 – 1)3
= 1003 – 13 – 3(100)(1)(100 – 1)
= 1000000 – 1 – 30000 + 300
= 100300 – 30001
= 970299

If a straight line falling on two straight lines makes the interior angles on the same side of it taken together less than two right angles, then the two straight lines, if produced indefinitely, meet on that side on which the sum of angles is less than two right angles.
