Answer:

60

Explanation:

Ray PQ strikes the mirror AB at Q and gets reflected along QR according to the laws of reflection. The ray QR incident on mirror BC makes an angle of 30° with the mirror.

So, the angle of incidence on this mirror is 90° - 30° = 60°. Hence, the angle of reflection is also 60°.
