Answer 2

Answer:

55°

Explanation:

If we draw the diagram,given angle is incident on the surface 55° with respect to the plane.

If we consider the normal at the point of incidence..

The angle made by the incident ray with the normal is (90-55)=35°

As the mirror law states angle of incidence = angle of reflection

The reflected ray makes an angle of 35° with respect to normal.

Thus the angle made by the reflected ray with respect to the plane surface

is (90-35)=55°
