So I think that 4/sqrt 2 will give you s

Another way to get to the same answer is to cross multiply with ratios. Your 45/45/90 triangle has a side ratio of 1/1/sqrt(2). Since you know the hypotenuse you can set it up as what you know over the scaling factor. \[\frac{Unknown~Leg}{1}=\frac{Known~Hyp~Value}{\sqrt{2}}\]Solve for the unknown.
