Answer:
∠A' = 115°
C is correct
Step-by-step explanation:
Peter reflected parallelogram ABCD across the y-axis.
∠A is 115° and ∠B is 65°
In reflection the property of figure doesn't change.
The given figure is parallelogram ABCD.
Reflection about y-axis.
Change in coordinate of ABCD.
The length of side of parallelogram and angle of parallelogram would be same.
Therefore, the measurement of ∠A' = ∠A
∠A' = 115°
Hence, the degree measurement of ∠A' is 115°
