    I have come to the conclusion that w is also 7√3 because of the 30,60,90 theorem.

    so yeah, your right the triangle is a 30 60 90 triangle. now do you know what the theorem states?

    Yes. I believe the pattern is to find the hypotenuse and the long leg.

    we know from the sketch that Cos(30)=(7/root (3))/w then you can make w the subject of the formula . Done

    Wait. \[Cos30 =7/\sqrt 3 / w = 14\]

    w=7/(sqr(3)cos(30))
