Question

here is the complete diagram​

Answer 1

Answer:

the angle between incident ray and reflected ray is 120 degrees check in the attachment

Answer 2

${\huge{\underline{\red{Answer:}}}}$

Angle between incidence angle and reflected angle = ${120°}$

${\huge{\underline{\pink{Given:}}}}$

Angle between incidence angle and mirror = 30°

${\huge{\underline{\blue{Formula:}}}}$

Angle of incidence = Angle of reflection

${\huge{\underline{\green{Solution:}}}}$

Angle AON = 90° - 30° = 60°

Angle between incidence angle and reflected angle = 60° + 60° = 120°
