Calculate the area ofcolourful Part.​

Answer»

Given: LENGTH and breadth of a rectangle are 14m and 26m.

Now,

we have to find the EXTERNAL area of a rectangle

By using FORMULA: Length × breadth

external area= 14m ×26m

= 364m2

So,

External area of a rectangle is 364m2

Now,

we have to find internal length and breadth of a rectangle

By using formula: external length and breadth - width of a rectangle

Internal length = 26m -3m

= 23m

Internal breadth = 14m - 3m

= 11m

Now,

we have to find internal area of a rectangle

By using formula: length × breadth

Internal area= 23m × 11m

= 253m2

SO,

Internal area of the rectangle is 253m2

Now,

we have to find the area of colourful part

By using formula:(External -Internal) area of the rectangle

According to the question

=(364- 253) m2

= 111m2

Hence,

The area of colourful part is 111m2

Answer»

Answer:

Step-by-step EXPLANATION:

HOPE it helps friend

a=√2+1/√2-1 * √2+1/√2-1

=(√2+1)^²/2-1 = 2+1+2√2/1

So, a=3+2√2

And b=1/a= 1/3+2√2

a+b= 3+2√2 + 1/3+2√2

= (3+2√2)(3+2√2)

+1/3+2√2

=9+6√2+6√2+8+1/3+2√2

Factorise. 21x^2-2x+1/21​

Answer»

ANSWER:

hey!

Step-by-step explanation:

21x^2-2x+1/21​

we usually avoid factorising fractions!

so, multiply 21 to the equation

We will get

441x^2 - 42x+1

a*B = 1

a+b= -42

therfore

441x^2 - 21x-21x + (1)

=>   (21x)^2 - 2 * 21x + +(1)^2

=> a^2 - 2ab + b^2 => (a-b)^@

=> (21x -1) ²

=>(21x -1)(21x - 1)

=> (x -1/21)(21x - 1)

hope it helps

3xーy=24,4x+3y=48 solve it​

Answer»

Answer:

Step-by-step EXPLANATION:

Simplifying

4x + -3y = -24

Solving

4x + -3y = -24

Solving for variable 'X'.

Move all terms containing x to the LEFT, all other terms to the right.

Add '3y' to each side of the equation.

4x + -3y + 3y = -24 + 3y

Combine like terms: -3y + 3y = 0

4x + 0 = -24 + 3y

4x = -24 + 3y

Divide each side by '4'.

x = -6 + 0.75y

Simplifying

x = -6 + 0.75y

(b) If the same pair of values of x, y satisfy the three equationsax +by + c = 0bx + cy+a = 0cx + ay +b = 0then find the relation between a, b,c ​

Answer»

Answer:

ax + by + c + bx + cy + a + cx + ay + B = 0

ax + ay + a + bx + by + b + cx + cy + c = 0

a(x + y + 1) + b(x + y + 1) + c(x + y + 1) = 0

(x + y + 1)(a + b + c) = 0

Assuming, (a + b + c) = 0, we get,

a + b = -c ... (1)

Cubing both sides,

a^3 + b^3 + 3ab(a + b) = -c^3

a^3 + b^3 + 3ab(-c) = -c^3 ... from EQ. (1)

a^3 + b^3 - 3ABC = -c^3

a^3 + b^3 + c^3 = 3abc

If, (x + y + 1), then a,b and c doesn't satisfy the given equation.

Prove that angle opposite to equal sides of an isosceles triangle are equal​

Answer»

Required to prove :-

Angles opposite to equal sides of an isosceles triangle are equal.

Construction :-

Join A to D such that BD = CD which makes AD as the altitude .

Proof :-

Diagram :-

\setlength{\unitlength}{30} \begin{picture}(6,6)\put(2,1){\line(1,0){5}}\put(2,1){\line(1,1){2.5}}\put(7,1){\line(-1,1){2.5}}\put(4.5,1){\line(0,1){2.5}}\put(2,0.5){$ \tt C $}\put(7,0.5){$ \tt B $}\put(4.5,3.7){$ \tt A $}\put(4.5,0.5){$ \tt D $}\end{picture}

Consider ∆ ABC ;

∆ ABC is an isosceles triangle .

In which , AC = AB

we need to prove that ;

\tt{ \angle C = \angle B }

In order to prove this . First we need to prove that the two TRIANGLES i.e. ∆ ADC & ∆ ADB are CONGRUENT with each other .

So,

Consider ∆ ADC & ∆ ADB

In ∆ ADC & ∆ ADB

AD = AD

[ Reason :- Common Side ]

CD = DB

[ Reason :- By construction ]

AC = AB

[ Reason :- Given information ]

So,

By SSS congruency criteria

we can say that ;

∆ ADC \cong ∆ADB

This implies ;

\tt{ \angle C = \angle B }

[ Reason :- CORRESPONDING parts of congruent triangles ]

Hence,

It is PROVED that the angles opposite to equal sides of an isosceles triangle are equal .

Additional Information :-

The CONVERSE of the above theorem is ;

If the opposite angles of an isosceles triangle are equal then the opposite sides are also equal .

While solving these proof. The congruency rules are ver useful .

Some of them are ;

  • SSS ( Side , Side , Side )

  • AAA ( Angle , Angle , Angle )

  • SAS ( Side , Angle , Side )

  • ASA ( Angle , Side , Angle )

  • RHS ( Right angle , Hypotenuse , Side )

Here,

AAA rule is not mostly accepted rule .

Some of the important theorem which are useful while solving these proofs are ;

  • Thales theorem

  • Mid point theorem

Find the estimated question for 83 divided by 17​

Answer»

Step-by-step explanation:

DirectoryDivisible

How to calculate 83 DIVIDED by 17

Long Division

Here we will show you step-by-step with detailed explanation how to calculate 83 divided by 17 using long division.

Before you CONTINUE, note that in the problem 83 divided by 17, the numbers are defined as follows:

83 = dividend

17 = divisor

Step 1:

Start by setting it up with the divisor 17 on the left side and the dividend 83 on the right side like this:

1 7 ⟌ 8 3

Step 2:

The divisor (17) goes into the first DIGIT of the dividend (8), 0 time(s). Therefore, put 0 on top:

0

1 7 ⟌ 8 3

Step 3:

Multiply the divisor by the result in the previous step (17 x 0 = 0) and write that answer below the dividend.

0

1 7 ⟌ 8 3

0

Step 4:

Subtract the result in the previous step from the first digit of the dividend (8 - 0 = 8) and write the answer below.

0

1 7 ⟌ 8 3

- 0

8

Step 5:

MOVE down the 2nd digit of the dividend (3) like this:

0

1 7 ⟌ 8 3

- 0

8 3

Step 6:

The divisor (17) goes into the bottom number (83), 4 time(s). Therefore, put 4 on top:

0 4

1 7 ⟌ 8 3

- 0

8 3

Step 7:

Multiply the divisor by the result in the previous step (17 x 4 = 68) and write that answer at the bottom:

0 4

1 7 ⟌ 8 3

- 0

8 3

6 8

Step 8:

Subtract the result in the previous step from the number written above it. (83 - 68 = 15) and write the answer at the bottom.

0 4

1 7 ⟌ 8 3

- 0

8 3

- 6 8

1 5

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 83 divided by 17 calculated using Long Division is:

4

15 Remainder
