The angle of incidence of a ray of light on a plane mirror is 55^o. Determine the angle between the reflected ray and the mirror

angle of incidence= angle of reflection
angle of reflection = angle between normal and reflected ray
so the angle between reflected ray and mirror = 90-55=35degrees

The selected answer is wrong:

For a plane mirror, angle of incidence and reflection is the same. Hence the angle between reflected ray and mirror(glancing angle) will be 100-55=45 not 35
