Question

please answer bta do is question k​

Answer 1

Answer:

65°

Explanation:

because the angle of incidence =25°

and angle I = angle r

angle of reflection =25°

the ray then makes an angle of 65° with the mirror

after reflection the ray makes a triangle after again incidence at mirror b

then in that triangle

65+90+x=180

x+155=180

x=180-155=25

the angle made with mirror b is 25°

then the angle incidence at mirror b=65°

the angle of reflection =65°
