Answer:
[tex]x=25[/tex]
Step-by-step explanation:
These angles are supplementary meaning if you add them together they will equal 180
So we add the 2 equations together and set it equal to 180 and then find x
[tex](2x+10)+(4x+20)=180[/tex]
Combine like terms
[tex]6x+30=180[/tex]
Subtract 30 to both sides
[tex]6x=150[/tex]
Divide both sides by 6
[tex]x=25[/tex]
