Answer:
"refr the attachment
Step-by-step explanation:
Let the coordinates of point A be (a, 0). Draw a line (AL) perpendicular to the x-axis. We know that angle of incidence is equal to angle of reflection. Hence, let ∠BAL = ∠CAL = Φ Let ∠CAX = θ ∴∠OAB = 180° – (θ + 2Φ) = 180° – [θ + 2(90° – θ)] = 180° – θ – 180° + 2θ = θ ∴ ∠BAX = 180° – °
