It seems like you're asking for help in finding the value of \( x \) in a geometry problem related to angles or shapes, possibly involving a square and other given angles, such as 58 degrees.
If you can provide more context or clarify the relationship between \( x \), 58 degrees, and the square (for example, if they are angles in a certain geometric configuration), I would be glad to help you find the value of \( x \).
