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

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

Is that right?

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