Answer:
x = 9
y = [tex]9\sqrt{2}[/tex]
Step-by-step explanation:
Since there is a 45° angle and a 90° angle, this is a isosceles triangle, therefore x = 9 and you can find y by pithagoras:
9² + 9² = y²
81 + 81 = y²
y = [tex]\sqrt{162}[/tex]
[tex]y=\sqrt{2 * 81}[/tex]
[tex]y=\sqrt{2 * 9^2}[/tex]
[tex]y=9\sqrt{2}[/tex]
