Answer 2

Answer:

$5x+80=180$
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 $3x+80+2x =180$.

But there are coefficients that share the same variable.
So by simplifying the equation, you end up with:

$5x+80=180$
