Best ResponseYou've already chosen the best response.1Knowing that, you can use Pythagoras to solve for \(x\). Being across from the 60º angle, would it be the long leg or the short leg?

Best ResponseYou've already chosen the best response.1That's what I get, yes, since \(\large x = \frac{\sqrt{3}}{2}(h)\)

Best ResponseYou've already chosen the best response.1As I said, yes. \[\large x = \frac{\sqrt{3}}{2}(h) = \frac{16\sqrt{3}}{2} = 8\sqrt{3}\]
