    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?

    x > 90

    for pretty much the same reason as above
