Answer:

According to first law of reflection incident and reflected angles are equal. So, reflected angle will be 30 degrees. Reflected angle and angle B together make up the angle between normal and the surface that is 90 degrees. So, Angle b = (90 - reflected angle), which is (90-30) = 60 degree.
