Best ResponseYou've already chosen the best response.0To solve the short leg (x), plug in H for the first formula.

Best ResponseYou've already chosen the best response.0We don't really need sin and cosine for this one, since we have a 306090 triangle. Ez mode

Best ResponseYou've already chosen the best response.0In the diagram \[\large H=4\sqrt{2}\] So plug that into \[\large SL~=~\frac{1}{2}H\]

Best ResponseYou've already chosen the best response.0those numbers you are using came form sin and cos

Best ResponseYou've already chosen the best response.0just wanted to point that since you said no need for sin and cos so just for the poster to be cleared where those came from

Best ResponseYou've already chosen the best response.0Yep. So what would we get from that?

Best ResponseYou've already chosen the best response.0Yeah, although it may be easier to leave it in the form of \(2\sqrt{2}\) for now.

Best ResponseYou've already chosen the best response.0Now that we know that \(SL = 2\sqrt{2}\) we can plug it into the next formula \[\large LL~=~SL\sqrt{3}\]

Best ResponseYou've already chosen the best response.0so it would be 2sqrt2 * Sqrt 3 ???

Best ResponseYou've already chosen the best response.0Yes. \[\large 2\sqrt{2 \times 3}\]
