The term "mirror of your reflection" has no meaning, except possibly in prose. The word "reflection" can mean "an image seen in a mirror". Examples: "I looked in the mirror and saw my reflection." "After weeks marooned on the island, he barely recognized his own reflection in the mirror."
If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
