Answer:
150° CCW
Step-by-step explanation:
Apparently, we are to assume that segment A'B' is a reflection across line m, and that segment A"B" is another reflection across line p. Then the total angle of rotation is double the angle between lines m and p. The smaller angle is the supplement of 105°, so is 75°. Double that is 150°
The angle of rotation to get from A to A" is 150°.
__
The center of rotation is the point of intersection of p and m.
