    Answer:

    This question is vague because it doesn’t specify whether 20° is the angle of incidence or the angle the ray makes with the surface

    But If we consider 20° as the angle of Incidence…

    The Angle of Reflection = 20° also

    Because

    From The Law of Reflection

    Angle of Incidence = Angle of Reflection
