help me figure out the equation

Answer:
Step-by-step explanation:
In the given question, the relationship between the pair of angles AXC and ZBXC can be determined as follows: - **Choice C: They are vertical angles.** Explanation: - Vertical angles are opposite angles formed by two intersecting lines. In this case, angles AXC and ZBXC are vertical angles because they are opposite each other and formed by the intersection of lines XB and AC. - Vertical angles are always congruent, which means they have the same angle measure. So, angles AXC and ZBXC have equal measures and are classified as vertical angles. Therefore, the relationship between the pair of angles AXC and ZBXC in the diagram is that they are vertical angles.
