Answer:
The light is reflected at an angle of 30 degrees from the second mirror.
Explanation:
The situation is shown in the attached figure
As ย we know that angle of incidence equals angle of reflection thus all the angles are calculated in the same manner
Angle i = 70 Thus angle r = 70 as angle of incidence and reflection are same
In triangle BFC
angle FCB equals 180 - 100 - 20 = 60 degrees
Thus The angle i' equals 90 - 60 =30 degrees
Thus the final angle of reflection is also 30 degrees.
