Which angle number is a vertical angle to ZGKJ? B C/3 \E A 2 5\6 O. G ZA H K M J

Answer:
∠NKL = angle 12
Explanation:
Vertical angles are opposite angles that are formed when two lines cut each other.
Therefore, a vertical angle to ∠GKJ is ∠NKL because they are formed when lines GL and OJ cross.
So, the answer is angle 12
