Answer:

Step-by-step explanation:

CO prime no. Are the no. Which have HCF 1

ANSWER:

His SALARY will DECREASE to 25%

Surface area of CUBE is GIVEN by the formula 6A2
so 6a2 =586
a2 =586÷6
=97
THEREFORE a= 97 ×97×97
=912673

ANSWER:

Step-by-step EXPLANATION:

Perimeter=2(l+B)

236cm=2(72cm+B)

236cm/2=72cm+B

118cm-72cm=B

46cm=B

ANSWER:

Step-by-step EXPLANATION:

Answer:weight of 72 books =9KG weight of1book = 72\9=8 so weight of 1 book is 8 now weight of 80 books = 8multiplied by 80=640

Step-by-step EXPLANATION:

Given: 171kg 500g = 171500 grams.

⇒ 3 hours = 171500 grams.

⇒ 1 hour = 171500/3

               = 57166.67.

So,60 minutes = 57166.67

1 MINUTE = 57166.67/60

               = 952.77.

Hope this HELPS!

ANSWER:

Step-by-step EXPLANATION:no

His SALARY will DECREASE to NEARLY 25%

Let the NUMBERS = x and y
sum of two digit no =8
so-----
x+y=8_________equation 1.
difference between number and its REVERSE

(10x+y) -(10y+x)=18
9x-9y=18
x-y=2___________equation 2.

solve equation 1. and 2.
x+y=8
x-y=2
2x=10
x=5
hence y =3

Given :

The ratio of the the supplementary ANGLES = 2:3 .

To Find : MEASURE of the angles .

Solution :

Let the angles in the FORM of X .

2x and 3x


Now,

According to the question :

2x+3x = 180°
5x = 180°
x= 180/5 = 36°

Now angles : 2x = 2*36°= 72°

3x = 3*26 = 108° .

This is the ANSWER for this QUESTION

Question no.(3) , Given Angles are

A = 2y + 4° , B = 6x - 4°

C = 4y - 4° , angle D = 7x + 2°

sum of opposite angles of given cyclic

quadrilateral will be equal = 180°

Angle A + angle C = 180°

2y + 4° + 4y - 4° = 180°

6y = 180° => y = 30°

Angle A = 2y + 4° = 2(30) + 4 = 64°

amgleC = 4y - 4° = 4(30) - 4° = 116°

AngleB + AngleD = 180°

6x - 4° + 7x + 2° = 180°

13x = 182 => X = 14

thus

AngleB = 6x - 4 = 6(14) - 4

AngleB= 80°

and AngleD = 7x + 2° = 7(14) + 2= 100°

angle D = 100°

Answer:all the angles of cyclic quadrilateral ABCD are A = 64°,B = 80°,
C = 116°, D = 100°

question.no (4):
-------------------------

given AB is parallel to CD

AB = 10CM , CD = 24cm

in quadrilateral ABCD ,

radius of circle = 13cm = OC = OA

CD = 24cm,then CE = 24 / 2 = 12cm=ED

in triangle COE,

(CO)^2 = (CE)^2 + (OE)^2

(13)^2 = (12)^2 + (OE)^2

OE^2 = 169 - 144 = 25

=> OE = √25 = 5cm

so thus , OE = 5cm

now in triangleAOF

since, AB = 10cm ,AF = 10/ 2 = 5cm = BF

(AO)^2 = (OF)^2 + (AF)^2

(13)^2 = (OF)^2 + (5)^2

(OF)^2 = 169 - 25 = 144

OF = √144 = 12cm

therefore,

the shortest distance between AB and CD

EF = OE + OF

EF = 5cm + 12cm = 17cm

Answer: shortest distance = 17cm

Here is your SOLUTION

Given :-

Radius 6 CM .
ANGLE of the SECTOR is 60°

To find the area os sector of a circle :-

Area of sector = θ/360° × πr^2
=>60°/360° × 3.14 ×6×6
=>1/6×3.14×36
=>3.14×6
=>18.84Cm^2

Hence

The area os sector of a circle is 18.84 cm^2

Hey mate !!❤✌
here's ur ANSWER ⤵⤵

in every LINE ( horizontally from left to right)
the sum of nos. is 15
so in ORDER to make the sum 15
let the required no. be X
1+5+x = 15
6+x = 15
x = 15-6



⭐ HOPE it helps

What??¿????¿‽¿
what is this

Let the ONE angle be 'x'

other angle = TWICE of x = 2x

sum of SUPPLEMENTARY angles = 180°

x + 2x = 180°


3x = 180°


x = 60°

Answer: required angle = 60°
