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
