Here is an explanation:
The angle of incidence in the mirror 1 is
at angle 90 to the angle 30 provided. so
subtracting 90 from 30 angle of incidence is 60
which is equal to angle of reflection. the angle
of reflection is also at 90 to the other glance
angle making the other glance angle of the
reflected ray 30. Then using rules of lines and
angles the glance angle is alternate to the
incident ray of m2 and angle of incidence is
equal to angle of reflection in m2. so angle of
reflection in m2 is 30 degree. myschool is100%

REF: My mentor taught me that got no reference as at now.
The answer is correct, by applying maths method, The incident ray and reflected ray are parallel to each other, therefore, the angle of incidence corresponds with the angle of reflection (corresponding angles)
