The angle of incidence equals the angle of reflection. Therefore, if your angle of incidence is 15 degrees, your angle of reflection equals that also. If it is 45 degrees, your angle of reflection is also 45 degrees, and so on.
yes
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
We know angle of incidence = angle of reflection. Hence, angle of incidence will be 24/2 = 12 degrees. (which is also angle of reflection)
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
