Question

Pls answer with explanation and step

Answer 1

Answer:

angle of incedent= angle of reflection= 60°

Explanation:

ON is perpendicular to miroor and makes 90° angle both side

so,

in the aid of incedent ray,

let's suppose angle of incedent be x.

so,

x + 30 = 90°

x= 60°

and we now that angle of incedent and angle of reflection is equal due to law of reflection .

so , angle of incedent= angle of reflection= 60°

please mark me as brainliest. this is the right answer
