Explanation / Answer

Incident and refracted ray makes equal angle from normal to the plane mirror, since angle between incident and refracted ray is 54. Hence angle between incident ray and normal is 27°.since the angle between reflected ray and plane is theta, and reflected ray and normal is 27.

Hence theta=90-27=63
