Answer:

x = 24

Step-by-step explanation:

A 45- 45- 90 triangle is isosceles ( base angles congruent )

The the legs are congruent , both 12 $\sqrt{2}$

Using Pythagoras' identity in the right triangle , then

x² = (12 $\sqrt{2}$ )² + (12 $\sqrt{2}$ )² = 288 + 288 = 576 ( take square root of both sides )

x = $\sqrt{576}$ = 24
