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» hey! Step-by-step explanation: 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. Read more on Brainly.in - brainly.in/question/4669292#readmore |

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 :-Consider ∆ ABC ; ∆ ABC is an isosceles triangle . In which , AC = AB we need to prove that ;
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 This implies ;
[ 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 ;
Here, AAA rule is not mostly accepted rule . Some of the important theorem which are useful while solving these proofs are ;

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 plz mark as brainliest please |
