| The angle between the incident beam and the reflected
A = An + Ao.
According to the law of light reflection, the angle of incidence is equal to the angle of reflection, which means you can write
A = 2 * Ap.
From the formula, select and calculate the required
Ap = A / 2;
Ap = 90/2 = 45.
Answer: The beam should fall at an angle of 45 degrees.
