Answer:
[tex]5x+80=180[/tex]
I hope this helps and that you can give a brainliest!
Step-by-step explanation:
This is a straight line which is always 180°.
Here there are 3 angles adding up to the total 180°.
So the initial equation is [tex]3x+80+2x =180[/tex].
But there are coefficients that share the same variable.
So by simplifying the equation, you end up with:
[tex]5x+80=180[/tex]
