According to the law of reflection, the angle of incidence and angle of reflection are equal. Both these angles are measured with respect to a line normal to the reflection surface. Ray of light strikes the mirror at an angle of 30°. ⇒ It will make an angle of 60° (90° - 30°) with the normal. As shown in the figure below. 
$\therefore$ Angle of incidence = 60°.
Now, By laws of reflection; Angle of Incidence = Angle of reflection; ⇒ Angle of reflection = 60°. Hence Angle of reflection is 60°.
$\therefore$ Angle of incidence = 60°.Now, By laws of reflection; Angle of Incidence = Angle of reflection; ⇒ Angle of reflection = 60°. Hence Angle of reflection is 60°.
