Answer:
50°
Step-by-step explanation:
The law of reflection states that when a ray light reflects off a surface, the angle of incidence is equal to the angle of reflection.
~~~~~~~~~~
The angle of incidence is 50°
∠PQR = the angle of reflection + the angle of incidence
m∠PQR = 100° ⇒ measure of the angle of incidence = 50°
