Expert Answer:

As the angle of reflection and angle of incidence are same.
The reflected ray forms an angle θ which is equal to the angle made by the mirror with the horizontal 
They form alternate angle because both have the same angle θ.
Hence reflected ray is parallel to horizontal which implies that reflected ray has zero angle with the horizontal
