(y+x)° 2x° (y-x)° what's the answer plz

Remark

Vertically opposite angles are equal, which means that 2x = y - x

Side by side angles are supplementary which, in this case 2x + (y + x) = 180o

Solution

From the first equation we get

2x = y - x     Add x to both sides.

2x + x = y

3x = y

From the second equation we get

2x + (y + x) =  180     Remove the brackets

2x + x + y = 180

3x + y = 180             Substitute 3x = y in this equation

3x + 3x = 180

6x = 180

x = 180/6

x = 30

y = 3x

y = 3*30

y = 90

Answer

x = 30

y = 90

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
