Question

Find the angle of incidence and angle of reflection from the following figure​

Answer 1

Answer:

0 is the answer mark me as brainlist

Answer 2

Answer:

angle of incidence and reflection= 70 degree

Explanation:

the normal is a perpendicular. thus the angle between normal and the mirror is 90.

thus angle of incidence= 90-20 = 70 degree.

by laws of reflection, i=r = 70
