Answer:

25

Step-by-step explanation:

These angles are supplementary, or add up to = 180 degrees:

(2x + 10) + (4x + 20) = 180

6x + 30 = 180

6x = 150

x = 25

Let's check our work:

2(25) + 10 = 60

4(25) + 20 = 120

60 + 120 = 180 degrees :)

Good luck!

Answer:

x = 25

Step-by-step explanation:

[tex](2x+10)+(4x+20)=180^{o}[/tex]

[tex]6x+30=180[/tex]

[tex]6x=180-30[/tex]

[tex]6x=150[/tex]

[tex]x=150/6[/tex]

[tex]x=25[/tex]

Hope this helps
