Question

AB is a mirror,POis the incident ray and OR,the reflected ray.if angle POR=112°find angle POA

Answer 1

hey here is your answer

Answer 2

the figure for the question is attached

construction:

draw NO as normal

thus

angle PON= angle NOR [NO is the normal AND angle of incidence is equal to angle of emergence ]

angle NOR =56°

angle NOA = 90° [NO is the normal and normal is a perpendicular bisector]

angle NOR + angle ROA= angle NOA

90°-56°= ∠ROA

34°= ∠ROA

∠ROA +∠NOR = ∠POA

∠POA = 146°
