2x-y=103x+y=5

Add

5x=15x=15/5=3

y=2x-10y=6-10=-4

We know that the sum of the interior angles of a triangle is 180 °.then, A+B+C=180° A+B+30°=180°A+B=150°so, A=B=75° (Given, A=B)find the value of x and y ,x=180°-75°=105° ....( from external Angle.) y=180°-75°=105°

Hence, x=y=105°

Sir please tell me the answer of the (III) part

Smallest number exactly divisible by 12,20,224 and 32 is their LCM.

Prime factorisation:

12 =2*2*320 =2*2*524=2*2*2*332=2*2*2*2*2

LCM is given by the product of prime factors, each raised by the highest exponent. As 2 occur maximum 5 times, 3 and 5 occur one time each.

LCM =2*2*2*2*2*3*5 =480

Hence, the required smallest number is 480.

its wrong answer is 242.2

it's wrong answers. its answers is 242.2

IT'S RIGHT ANSWER IS =1211/160=7.56875

7.56875 is the correct answer

HCF of 468 and 222

468 = (222 x 2) + 24222 = (24 x 9) + 624 = (6 x 4) + 0

Therefore, HCF = 6

6 = 222 - (24 x 9)= 222 - {(468 – 222 x 2) x 9 [where 468 = 222 x 2 + 24]= 222 - {468 x 9 – 222 x 2 x 9}= 222 - (468 x 9) + (222 x 18)= 222 + (222 x 18) - (468 x 9)= 222[1 + 18] – 468 x 9= 222 x 19 – 468 x 9= 468 x -9 + 222 x 19

Hence, HCF of 468 and 222 in the form of 468x + 222y is 468 x -9 + 222 x 19

This factsheet looks at three specificexamples of 3D shapes, defining them and giving a recognisable real lifeexample. This factsheet looks at cubes, pyramids and cylinders, but could be extended to look at othershapesincluding cuboid, sphere, cone, prism, etc.

1 you will do construction join BD.after construction u will see that trapezium and triangle is formed and take length of BD be 5 cm. use formula of triangle and trapezium. then add all the values u will get the answer

a) Perimeter = sum of all sidesPerimeter = (3+3+3+5+5) = 19 cm

b) Perimeter = sum of all sidesPerimeter = 3 × 5.5 cm = 16.5 cm

right answer hai aapka -1

For commuative a * b = b* a ,let take a = 5 and b = -6a * b = 5 + 2 × (-6) = 5 -12 = -7b* a = -6 + 2×(5) = -6 + 10 = 4So, a * b is not equal to b* a, so not commuative.

Given:a*b= LCM of a and bNow12 = 2 × 2 × 320 = 2 × 2 × 5

LCM = 2 × 2 × 3 × 5

LCM =60

This a*b=60

full explain

samajh nii Aya

thanks a lot

First we will find the hcf. Since 65>45 Therefore, 64=40×1+25 40=25×1+15 25=15×1+10 15=10×1+5 10=5×2+0 Since remainder is 0 Therefore hcf is 5 To do it in linear combination we have 5=15-(10×1) 5=15-(25-15×1) 5=40-25×1-(25-40×1-25)... And so on till we get 5=40(5)+65(-3) Now comparing 40x+65y with our ans we get that , x=5 and y=-3

Thank you , yo man

HCF of 40, 65 =

40 = 2³ × 5

65 = 13 × 5

HCF = 5

So, d = 40x + 65y

5 = 40 × 5 + 65 × (-3)

So, x = 5 and y = -3

Ans :- A shape is the form of an object or its external boundary, outline, or external surface, as opposed to other properties such as color, texture or material composition.

the answer of your question is 555

आपके प्रश्न का उत्तर 555

let x =√-2+2√-2+2√....∞here √-2+2√ is repeating so it can be substituted as x so, x = √(-2+2x) => x²= -2+2x so, x²-2x+2 = 0 => x = 2±√4-4.(2)/2 = 1±2i the value of x = 1-2i , 1+2i.

yes it is a binary operation

thanx bro

5.1 5.2 .5.3 5.4 5.5

HCF of 468 and 222

468 = (222 x 2) + 24222 = (24 x 9) + 624 = (6 x 4) + 0

Therefore, HCF = 6

6 = 222 - (24 x 9)= 222 - {(468 – 222 x 2) x 9 [where 468 = 222 x 2 + 24]= 222 - {468 x 9 – 222 x 2 x 9}= 222 - (468 x 9) + (222 x 18)= 222 + (222 x 18) - (468 x 9)= 222[1 + 18] – 468 x 9= 222 x 19 – 468 x 9= 468 x -9 + 222 x 19

Hence, HCF of 468 and 222 in the form of 468x + 222y is 468 x -9 + 222 x 19.

More specifically, a binary operation on a set is a binary operation whose two domains and the codomain are the same set.is the best answer

= A system in which information can be expressed by combinations of the digits 0 and 1. please like my answer ☺☺☺😊😊😊😊☺☺☺😊😊

The binary number system consists of only two digits, i.e., Zero and one.since this system uses two digits it has the base 2.

binary operation= contain two numbers=0, 1

In mathematics, a binary operation or dyadic operation is a calculation that combines two elements to produce another element. More formally, a binary operation is an operation of arity two.
