x = 7, y = 7root2/2

Step-by-step explanation:

All 45-45-90 triangles have the same side length relationships

https://www.dummies.com/education/math/geometry/identifying-the-45-45-90-degree-triangle/

Both sides across from the 45 are the same, so y = 7root2/2

The hypotenuse is the side times root2

So x = 7root2/2 * root2 = 7*2/2 or 7
