Question

In the figure PQ is a mirror AB is the incident ray and BC is the reflected ray. If angle ABC=46 degree, then angle ABP = ???​

Answer 1

Answer:

∠ABC=46°

We know that in a plane mirror,

the angle of the incident = angle of reflection.

⇒∠CBQ=∠ABP...(i)

Since, PQ is straight line

∴∠ABP+∠ABC+∠CBQ=180°

⇒∠ABP+∠ABC+∠ABP=180°

[from (i)]

⇒2∠ABP+46 ° =180°

⇒2∠ABP=180°−46° =134

⇒∠ABP= 134°/2

⇒∠ABP=67 °

Answer 2

Answer:

67 degrees
