When a point is reflected across the y-axis, the coordinates of the point change such that the x-coordinate is negated while the y-coordinate remains the same. This type of reflection does not affect angles, particularly those associated with shape or other angles in the figure.
Given that angle \( A \) measures 50 degrees, the reflection across the y-axis does not alter the measure of angle \( A \). Therefore, the measure of angle \( A' \) (the corresponding angle after reflection) remains the same.
Thus, the measure of \( A' \) is:
\[
\boxed{50}
\] degrees.
