To solve this problem we will resort to the concept of angle of incidence and refraction.

Since it is a reflection on a mirror, the angle provided for refraction will be equal to that of the incidence, that is, 25 °

The angle of reflation is always perpendicular to the surface so it is necessary to find the angle with respect to it.

$\theta = 90-25$

$\theta = 65\°$

Therefore the angle of the reflected beam of light made with the surface normal is 65°
