If you can you show step-by-step so i know how to better understand. you : ) will award brainliest

First method: isosceles triangle

This is a right triangle, so one angle is 90°. The other angle is 45. So, the last angle must be

So, the triangle is isosceles, and the legs have the same length, i.e. x=4.

Then, we can find y using either the pythagorean theorem, or the fact that a right isosceles triangle is half a square, and so y is actually the diagonal of the square:

First method: trigonometry

You can use the sine law: it states that the ratio between a side and the sine of its opposite angle is constant. In particular, with right triangles, we have

And similarly

and trivially deduce again that x=y=4.
