Answer:

a. x=4.2, y=3

Explanation:

We know the degrees of the two angles: Right angle (90 degrees) and 45 degrees.

The sum of the interior angles of a triangle is equal to 180 degrees, so the unknown angle is 45 degrees.

The two angles below are both 45 degrees, indicating that the side length is also 3.

So y is equal to 3, the answer can only be a.
