The image you have shared appears to be a geometric diagram showing a circle with various lines intersecting or contained within it. Specifically, there are points labeled A, B, C, D, and E with line segments connecting them to form various angles and triangles. The diagram indicates that the angle formed at D has a measure of 136°.
Typically, diagrams like this are used in geometry problems to solve for unknown angles, lengths, or other properties using geometric theorems and postulates. If you have a specific question about this diagram, such as how to find the measure of angle x at point A or the value of another variable in the diagram, feel free to ask, and I can guide you through the process of solving the problem.
