Answer:
This is a 45, 45, 90 triangle.
That means, x is equal to 12, since all 45, 45, 90 triangles are also isosceles, meaning that two of their sides are equal to each other.
To solve for y, we can use the Pythagorean theorem:
12^2 + 12^2 = y^2
288 = y^2
y=12[tex]\sqrt{2}[/tex]
Let me know if this helps!
