Thank you for sharing the image. Let me analyze the diagram and solve the problem.

The problem involves geometry, and the diagram shows:

1. A triangle $\triangle BDE$ inside a larger shape.
2. An angle of $48^\circ$ at $E$.
3. The line $BC$ is parallel to $FG$, and the angles near $B$ and $E$ likely relate to the property of parallel lines.

Key observation: Using the properties of parallel lines and the sum of angles in a triangle, we can calculate the value of $x$.

Let me confirm—would you like me to solve for $x$ (the missing angle), or are there additional instructions related to this diagram?

Relative Questions:

1. What is the sum of angles in a triangle?
2. How do the properties of parallel lines help in solving for $x$?
3. What is the alternate angle theorem in geometry?
4. How can adjacent angles at a straight line add up to $180^\circ$?
5. Would additional labeling or explanation of the diagram help?

Tip: In geometry problems, always look for relationships between parallel lines and transversals—such as alternate and corresponding angles!
