Answer:
Answer: Angle between incident & respected rays is 80 degree.
Incident angle = angle of incident ray to the normal.
Reflections angle=Angle of reflected ray to normal.
For any mirror, incident angle= reflections angle.
Angle between incident & reflections rays = incident angle + reflections = 40 + 40 = 80 degree.
