The light falls at an angle of 25 degrees to the surface of the flat mirror. what is the angle of reflection of the beam and the angle between the incident and reflected rays

∠γ = 25.
∠β -?
∠α + ∠β -?
According to the law of reflection: the angle of incidence ∠α is equal to the angle of reflection ∠β: ∠α = ∠β.
The angle of incidence of the ray ∠α is the angle between the incident ray and the perpendicular to the reflecting plane drawn to the point of incidence.
The angle of reflection of the beam ∠β is the angle between the reflected beam and the perpendicular to the reflective plane drawn to the point of incidence.
∠γ + ∠α = 90.
∠α = 90 – ∠γ.
∠α = 90 – 25 = 65.
∠β = 65.
∠α + ∠β = 65 + 65 = 130.
Answer: ∠β = 65, ∠α + ∠β = 130.
