Answer:

y = 7, x ≈ 9.9

Step-by-step explanation:

The remaining angle has to also be 45° which tells us we're working with an isosceles right triangle, or that y also has to be 7 (the same length).

Use the Pythagorean theorem for x.

a^2 + b^2 = x^2

7^2 + 7^2 = x^2

49 + 49 = x^2

x^2 = 98

x ≈ 9.9
