Inequalities with geometry
Write an equality for the possible values of x.

...help please... I don't know where to start, and they hardly give me any info. Which theorems do I need to find the inequality? And how do you find the inequality?

you mean an inequality, right?

how about 0 < x < 7

why is that?

Yes, I meant inequality... silly me. It makes sense the inequality you stated since the vertex with 7 as it's opposite side has a "plus 1", whereas the vertex with y[degree symbol] is only y.

So, naturally, the side with the bigger angle opposite itself must be bigger.

How about finding the inequality for this here lovely?
