Question

if the angel of incidence is 40 deegre then the angel of reflection will be​

Answer 1

If the angle between the incident ray and mirror is 40 degree , then the angle of incidence will be 50 degree. Then the angle of reflection will 50 degree ( angle of incidence = angle of reflection).

Answer 2

Answer:

The angle of incidence will be 50 degrees if the angle between the incident ray and the mirror is 40 degrees. The angle of reflection will then be 50 degrees (angle of incidence equals angle of reflection). As a result, 50 degrees plus 50 degrees equals 100 degrees.
