Expert Answer:

The light ray is making 30 to the power of 0 with the mirror 
Therefore it makes angle i equals 90 to the power of 0 minus 30 to the power of 0 equals 60 to the power of 0 with the normal
and according to the law of reflection
angle i equals angle r
Henceangle r equals 60 to the power of 0
