Best ResponseYou've already chosen the best response.1Ok, so what does that mean about our 2 angles 10x and 80  in the picture?

Best ResponseYou've already chosen the best response.1Can you set those 2 angles to add up to 180? Since they are supplementary, that way you can solve for x...

Best ResponseYou've already chosen the best response.0Well 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.

Best ResponseYou've already chosen the best response.1So we get \(\sf 10x + 80 = 180\)

Best ResponseYou've already chosen the best response.0So \[\large angle_{1}+angle_{2}=180\] Does that seem like a good representation of supplementary angles?

Best ResponseYou've already chosen the best response.1First, we will need to isolate the x. So what do we do about the '80' ? Do we add it or subtract it?

Best ResponseYou've already chosen the best response.1well you are adding it on the left hand side. What is the opposite of addition?
