Answer 2

Step-by-step explanation: In the diagram that is attached in the image provided, angles 1 and 2 are called vertical angles.

Vertical angles such as angles 1 and 2 share a common vertex which in this case is x and whose sides form opposite rays. Angles AXD and CXB would also be classified as vertical angles. When two lines intersect, they will always form two pairs of vertical angles.
