In the problem, we have a 45-45-90 right triangle. In this right triangle, the legs are congruent to each other. Thus, the value of y must be 7.
To find the value of x, we must find the length of the hypotenuse. To do that, we multiply one of the legs with the square root of 2.
[tex]7* \sqrt{2} \approx 9.9[/tex]
Since we have the value of the hypotenuse, we have the value of x.
Here are the final answers:
[tex]y=7[/tex]
[tex]x \approx 9.9[/tex]
Hope this helps! :)
