58 °
Step-by-step explanation
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface
so,According to the law of reflection, the angle of incidence equals the angle of reflection.
therefore,
if the angle of incidende =58°
then
therefore, the answer is 58 °
