Answer:</h2>
This is easy. All you need to do is set up a <u><em>proportional relationship</em></u>.
A proportional relationship uses variables to show similarities, in this case, in triangles.

<u><em>x</em></u> represents the missing side.
A can be converted since it is a repeating decimal
Because the ratio of a 45,45,90 triangle is 1:1: square root 2, x=4.

Now divide each side by d
dv/d = m/d
v = m/d
