Answer:

[tex]40^{\circ}[/tex]

Explanation:

The incident angle is [tex]20^{\circ}[/tex] so the reflected ray will also be [tex]20^{\circ}[/tex].

The normal divides the angle between the incident and reflected ray. So, the angle between them would be

[tex]\text{Incident angle}+\text{Reflected angle}=20+20=40^{\circ}[/tex]

So, the angle between the incident and reflected rays is [tex]40^{\circ}[/tex].
