please help me solve the problem

Answer:
x = [tex]\sqrt{2}[/tex] ; y = 2
Step-by-step explanation:
You have a 45 -45 - 90 triangle. There are two things to know"
1. The hypothenuse = leg × [tex]\sqrt{2}[/tex]
2. The legs are equal.
The hypothenuse is opposite the right angle that is "y" in this problem.
Hypothenuse = leg × [tex]\sqrt{2}[/tex]
= [tex]\sqrt{2} \sqrt{2} = \sqrt{4} = 2[/tex]
The legs are =
Therefore x = [tex]\sqrt{2}[/tex]
