fortytherapper · Answer

I have a way, but I don't know if it'll be confusing. I can try to explain if you want

anonymous · Answer

Please do, anything might be helpful.

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

anonymous · Answer

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

fortytherapper · Answer

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

anonymous · Answer

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

fortytherapper · Answer

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

anonymous · Answer

Okay now I understand.

fortytherapper · Answer

Nice! Lemme know if you can find x

anonymous · Answer

oh yes I got 125, which is correct. Hmm so I guess my mistake is setting the proportions.
