Answer:
a) 42° b)48°c)84°
Explanation:
a) according to laws of reflection
angle of incidence= angle of reflection
angle of reflection=42°
b) angle of normal ray with mirror is 90°
angle made by incident ray to the mirror= angle with normal - angle of incidence
= 90-42°
= 48°
c) angle between incident ray and reflected ray = sum of angle of incidence and angle of reflection
= 42° + 42°
= 84°
