angle of incident = 30°
angle of refraction = 30°
according to law of reflection,
the angle of incidence = angle of reflection.
angle of refraction = 30°
according to law of reflection,
the angle of incidence = angle of reflection.

Given, Angle of reflection = 30°
And Laws of reflection says:
Angle of incidence = angle of reflection
=> ∠i = ∠r
So, Angle of incidence = 30°
And Laws of reflection says:
Angle of incidence = angle of reflection
=> ∠i = ∠r
So, Angle of incidence = 30°
