So I first set up the proportion \[\frac{ 11 }{ (180-x) } = \frac{ 25 }{ x }\] Any questions on any of these values?

Well, it makes sense, I had set up the proportion wrong I guess. why minus x though?

Let's say one angle, x, is 12 degrees Supplementary angles equal 180 degrees, so the other angle is 180-12, or 180-x

ah I see, yes, so your proportion is saying?

It's saying that 11 is being compared to the smaller angle, and 25 to the largest. In order to find that, we must cross multiply and divide
