Question

please answer the question with explanation ​

Answer 1

Answer:

answer is 65 degree

Explanation:

because

the angle of incident at mirror A = 25 degree

angle of reflection at mirror A = 25 degree(let the other angle at mirror A be y= 65 because 90-25=65)

and the reflected ray [incident ray for mirror B]strikes the mirror B at an angle let be =x [let the other angle at mirror B = z]

(the reflected ray forms a triangle)

[sum of interior angle of triangle= 180 degree]

so z+90+65= 180

z= 180 - 90 - 65 = 25 degree

x=90 - 25 = 65 degree

i hope you understand if yes mark me as brainliest
