Answer:
[tex](5x-25)+55=180[/tex]
[tex]x=30[/tex]
Step-by-step explanation:
These 2 angles are on a straight line so they are supplementary so them added together will equal 180 so we can make an equation
[tex](5x-25)+55=180[/tex]
Now simplify
[tex]5x+30=180[/tex]
Subtract 30 on both sides
[tex]5x=150[/tex]
Divide both sides by 5
[tex]x=30[/tex]
I hope this helps
