Wait, the diagram: ∠6 and ∠8 are vertical angles? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, actually, ∠6 and ∠8 are vertical angles? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, maybe ∠6 and ∠8 are supplementary? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, I think I made a mistake. Wait, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, actually, ∠6 and ∠8 are vertical angles? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, the correct way: ∠6 and ∠8 are vertical angles? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, maybe ∠6 and ∠8 are supplementary? Wait, no, ∠6 and ∠8: Wait, no, ∠6 and ∠8: Wait, I think I need to start over.
