=>angle of incident+angle between these two angles+angle of reflection=180 degree
=>angle of incident+30+angle of reflection =180 degree
=>angle of incident +angle of reflection=(180-30) degree
=>angle of incident +angle of incident=150degree(since angle of reflection =angle of incident)
=>2 angle of incident=150degree
=>angle of incident=150/2
=>angle of incident=75degree=angle of reflection.
hope this is the required answer
