Answer:

x=5

Step-by-step explanation:

Since these are supplementary angles, we will have to add the two equations shown together to equal 180º.

[tex]12x+19+22x-9=180[/tex]

[tex]34x+10=180[/tex]

[tex]34x=170[/tex]

[tex]x=5[/tex]

Answer:

x=5

Step-by-step explanation:

we have,

12x+19+22x-9 = 180

34x+19-9 = 180

34x + 10= 180

34x = 180-10

34x = 170

x=170/34

x=5
