Answer 1

Answer:

$y=2\sqrt{2}$

Step-by-step explanation:

This is a 45-45-90 triangle. The relationship between the legs and the hypotenuse is H = L$\sqrt{2}$

Plug in the given information:

$4=y\sqrt{2}$

Solve for y:

$4=y\sqrt{2}$

$y=\frac{4}{\sqrt{2} }$

$y=\frac{4\sqrt{2} }{2}$

$y=2\sqrt{2}$
