Answer 1

Answer :

angle of incedence = angle of reflection

15 degree

Answer 2

Answer:

75 degree

Explanation:

straight line is equal to 180 degree

180-30=150 degree

150/2=75 degree.

as the 1st law of reflection

angle of incidence=angle of reflection.

so angle of incidence=75 degree

and angle of reflection=75 degree
