- Mitosis is a process where a single cell divides into two identical daughter cells (cell division). During mitosis one cell? divides once to form two identical cells. The major purpose of mitosis is for growth and to replace worn out cells.

Draw a diagram of reflection by a plane mirror.
see, that if mirror is rotated through an angle theta , the reflected ray turns through an angle two times theta.
this is due to the incidence and reflected both angles turning through theta. as the normal to the mirror also rotates.
in the present case
you are rotating the mirror through an angle 30 degrees, so the reflected ray will rotate in the above manner by an angle 60 degrees.
however you have also rotated incidence ray by 10 degree. if it is in the same direction as the turning of mirror , this will reduce the angle of incidence by 10 degree , so the actual rotation of the reflected ray will be reduced by 10 degree,
so finally you will get the reflected ray turned through
60 -10 = 50 degrees. "
