To solve for the missing variable, we would typically need more information about the image or the context of the problem. It seems like you're working with angles, possibly in a geometric figure or context.
If you can provide more details about the configuration or the relationships between these angles, I can help you determine the missing variable. For example, if these angles are related to a triangle, a polygon, or a specific geometric setup (like complementary or supplementary angles), let me know!
