$\sqrt{2$ Answer:

Step-by-step explanation:

take 45 degree as reference angle

use sin rule

sin 45=opposite/hypotenuse

1/ $\sqrt{2$ =x/2 $\sqrt{2$

do cross multiplication

x $\sqrt{2$ = $\sqrt{2$ * $\sqrt{2$

x $\sqrt{2$ =2

x=2/ $\sqrt{2$

x= $\sqrt{2$

pythagoras theorem

a^2+b^2=c^2

( $\sqrt{2$ )^2+y^2=(2 $\sqrt{2$ )^2

2+y^2=8

y^2=8-2

y= $\sqrt{6$
