see explanation

Step-by-step explanation:

The missing angle is 45°, thus the right triangle is isosceles.

Then the 2 sides y and 7 are congruent.

Hence y = 7

Using Pythagoras' identity to calculate x

x² = 7² + 7² = 49 + 49 = 98

Take the square root of both sides

x = $\sqrt{98}$ = $\sqrt{49(2)}$ = 7$\sqrt{2}$ ≈ 10
