Explanation / Answer
According to the chegg guidelines I am allowed to answer only 1 question at a time.
10 ) Here we need to determine the angle of incidence for the light ray shown approaching the plane mirror.
We know that the angle of incidence is that angle that is made with the normal so clearly from the image the angle is theta = 30 deg ( OPTION B) 30 DEG ) ======================ANSWER)
