Thank's bro 😊☺

let no.s be x and y

x-y=26

x=3y

3y-y=262y=26y=13

x=3yx=3×13x=39

Explanation : 1 g = 0.001 kg 60 kg 240 g = 60.240 kg (60.240)/12 = 5.02 kg = 5 kg 20 g

Solution : 5 kg 20 g

Concept : When opposite side are equal then opposite angles are equal.So, x = 40°

The supplement of angle 105° = 180° - 105° = 75°.

Let the angles of quadrilateral are x, 2x, 3x, 4x

Sum of all angles of quadrilateral = 360

Then,x + 2x + 3x + 4x = 36010x = 360x = 36

Angles of quadrilateral are36, 72, 108, 144

Therefore smallest angle = 36largest angle = 144

As order of A is 2×3 and order of B is 3×5

Order of (AB) is 2×5,

Order ( AB)' = 5×2

let the smaller angle be xand the larger be yy=x+18y-x=18y+x=1802y=198y=9999+x=180x=81

let two numbers be x and yx-y=26x=3y3y-y=262y=26y=13x=3*13x=39x=39,y=13

There is no contradiction. When we measure a length with scale orany other instrument, we only obtain an approximate rational value.We never obtain an exact value. For this reason, we may not realisethat eithercordis irrational. Therefore, thefractionc/d is irrational. Hence, π is irrational.

Woops Thanks 😋😊

Let the angles be x,2x,3x and 4x.

x+2x+3x+4x=36010x=360x=36

Smallest angle=x=36Largest angle=4x=4×36=144

28.314 - 31.427 + 113.928 = ? + 29.114

Let number to find be x142.242 - 31.427 = x + 29.114x = 142.242 - 60.541x = 81.701

Therefore, missing number is 81.701

1 leap year = 366 days 7/6 of leap year = 7/6*366 = 61*7 days = 61 weeks.

It is because when the current in your coil A is successfully changed, then the magnetic field linked with it also changes.

Hence, the overall magnetic field around the coil B also alters.

This kind of change in the magnetic field the lines around coil B actually induces the electric current in this field.

It is known as electromagnetic induction.

Numbers begin from 105 ....... 994

here a= 105l= 994n=?d= 7so994 = 105+(n-1) 7= 105+7n-7994= 98+7n994-98 = 7n896/7 = nn= 128

So , 128 three digit numbers are divisible by 7

Least 3 digit number divisible by 7 is 105The biggest 3 digit number divisible by 7 is 994

Sn= a+(n-1)d=>994= 105+(n-1)7=>7(n-1)= 889 {994-105=889}=>n-1= 127=> n=128...

The first number =105,last number=994,last term= a+(n-1)d,994=105+(n-1)7,889=(n-1)7,127=n-1,n=126

We have,PQRS as the given parallelogram, then PQ∥RS and PS∥QR.Since PQ∥RS and TS is a transversal, then∠PTS = ∠TSR (Alternate interior angles) .
