Problem

For a certain ray striking a plane mirror, the angle of incidence ii is given by (3x+10)∘(3x+10)^{\circ}, while the angle between the incident and reflected rays is specified as (8x−20)∘(8x-20)^{\circ}. (i) Establish an algebraic equation in xx that relates the given angles. (ii) Solve for xx. (iii) Using the value of xx, determine the numerical values of the angle of incidence and the angle of reflection. (iv) Verify quantitatively that the law of reflection is satisfied for this ray.
