Vertical angles are the angles that are opposite each other when two lines intersect. If you have the information on which angles correspond to ∠7 in the image, the vertical angle would be the one directly opposite to it.
Based on typical labeling in such diagrams:
- If ∠7 is positioned such that it is opposite to ∠5, then ∠5 would be the vertical angle to ∠7.
- Conversely, ∠6, ∠8, or ∠2 would not be vertical angles unless they are directly opposite to ∠7.
Without the actual image, you would select the angle opposite to ∠7 based on the diagram provided.
