Answer:
x = 
y = 
Step-by-step explanation:
Hello!
This is a right isosceles triangle (45°-45°-90°). You can solve for the missing angle by simply subtracting 45° and 90° from 180° (sum of angles in a triangle equals 180°)
Since the triangle is isosceles, x and y are congruent because they are the legs opposite to the congruent angles.
In a right isosceles triangle, the hypotenuse is always the measure of one leg multiplied by
.
So, let's use leg y, 
Solve for y:

y =
, which means that x is also
