Answer:
x = y = 2

Explanation:
the triangle is a 90- 45- 45 isosceles triangle with congruent legs, that is
x = y
using Pythagoras' identity in the right triangle
x² + y² = (2
)² , that is
x² + x² = 24
2x² = 24 ( divide both sides by 2 )
x² = 12 ( take square root of both sides )
x =
=
=
×
= 2

then
x = y = 2
