∠ α = 40.
∠ α + ∠ β -?
The angle between the incident and reflected rays will be the sum of the angle of incidence and the angle of reflection.
According to the law of reflection, the angle of incidence ∠ α is equal to the angle of reflection ∠ β: ∠ α = ∠ β.
Since ∠ α = 40, then ∠ β = 40.
∠ α + ∠ β = 40 + 40 = 80.
Answer: ∠ α + ∠ β = 80.
