    Two Angles are Supplementary if they add up to 180 degrees.

    Ok, so what does that mean about our 2 angles-- 10x and 80 -- in the picture?

    Can you set those 2 angles to add up to 180? Since they are supplementary, that way you can solve for x...

    Well if they're supplementary angles, and supplementary angles are angles that add up 180 degrees, I would think that adding those two angles would get you 180.

    So we get \(\sf 10x + 80 = 180\)

    So \[\large angle_{1}+angle_{2}=180\] Does that seem like a good representation of supplementary angles?

    First, we will need to isolate the x. So what do we do about the '80' ? Do we add it or subtract it?

    well you are adding it on the left hand side. What is the opposite of addition?
