    I was thinking it'd be bigger because of the 80 on smaller side idk

    it cant be 100 or 140 because there both to big so it ether 30 or 60

    There's only one possible option.

    This kind of problem confuses me because it doesn't add up to just 180.

    There's one specific clue. If you look at ∠OFG, you'll notice that it is very acute.

    so its 30

    But ∠OGF + ∠GOF + ∠OFG = 180° 40° + 110° + x = 180°

    Oh so when I add all the angles it does become 180

    The angles within a triangle must add to 180 in order for it to be a triangle.
