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
