Response:
D
Step-by-step explanation:
Response
The first diagram displays angles 1 and 2 as vertical angles.
Clarification
In all four diagrams, the initial one illustrates the vertically opposite angles.
Angles 1 and 2 are classified as vertically opposite because they face each other.
These angles maintain equal measurement when two lines intersect, resulting in four angles where two pairs of vertically opposite angles are formed.
In contrast, all other figures depict angles 1 and 2 as adjacent angles.
The expression evaluates to 54.
