Q.   While verifying the laws of reflection of sound, measured the angle between the incident sound waves and reflected waves as $54°$. Calculate the angle of reflection .

Dear Student

let angle of incidence be x,
angle of incidence = angle of reflection
therefore,angle of reflection = x
given that,
angle of incidence + angle of reflection=54
x+x=54
  2x=54
    x=54/2
    x=27
Therefore angle of incidence = angle of reflection = 27
