Question

find angle i and angle r if the angle between the mirror and the incident ray is 25 degree physics class 8th​

Answer 1

Answer:

65 degree

Step-by-step explanation:

angle on both sides with mirror is same so :

25+25=50 degree

now 180-50=130 degree as angles on a straight line

angle of incidence = angle of reflection

so 130/2=65 degree

Answer 2

Answer:

65 degrees

Step-by-step explanation:

90 - 25 = angle i = angle r

65 degrees = angle i
