A design for a stained glass window is shown. Find the value of \( x \).

To find the value of \( x \) in the design of a stained glass window, you might need to use properties of geometry or algebra, depending on what's given in the design—such as angles, lines, or shapes. For instance, if the window design involves triangles and you're given an angle measure that includes \( x \), you can apply the triangle sum theorem which states that all interior angles in a triangle add up to 180 degrees. Setting up an equation with the provided angles will allow you to solve for \( x \). If your design incorporates parallel lines and a transversal, remember that corresponding and alternate interior angles can help you set up relationships between angles to find the value of \( x \). Just keep a keen eye on the relationships and use the right angle theorems, and you’ll unlock the mystery of \( x \) in no time!
