The angle is 53.5 degrees.
What is a flat mirror?
A plane mirror is a mirror with a flat (planar) reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence.
This ques have been solved in two steps:
Step 1:
given that;
Θ=107 degrees
from figure,
∠BAC=180-ψ-(90-φ)
∠BAC= 90-ψ-φ
∠AOC=180-2(ψ-φ)-2φ
∠AOC=180-2φ
Step 2: part(a)
writing an expression for the psi at point o:
Θ+180-2ψ=180
2ψ=Θ
ψ=Θ/2
above is the expression for ψ
Step 3: part(b)
The angle of ψ is,
ψ=Θ/2
ψ=107/2
ψ=53.5 degrees
Hence, the angle is 53.5 degrees.

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.
Explanation:
It is given that,
Mass of the car, m = 875 kg
Initial speed of the car, u = 30 m/s
Brakes are applied i.e. v = 0
The car skids for 5.60 s in the positive x - direction before coming to rest, t = 5.6
(a) Acceleration of the car, 
(b) Force, F = ma
F = -4681.25 N
So, the force of 4681.25 N is acting on the car.
(c) Let x is the distance covered by the car. So,
x = 84.11 meters
So, the distance covered by the car is 84.11 meters. Hence, this is the required solution.
Atomic mass can change through the process of fusion. Another way is, it can also change in nuclear fusion.
