According to the law of reflection, if the angle of incidence of an incoming ray of light hitting a mirror is 27°, what is the angle of reflection for the same ray
leaving the mirror?
O A. 180°
O B. 63
O c. 27°
D. 153°
Plz help me

C. 27°

Step-by-step explanation:

This question can be solved by using the concept of law of reflection which states that any ray of light reflects from the surface then angle of incidence is equal to angle of reflection.

In the problem given above angle of incidence as given is 27 degrees.

therefore by using law of reflection angle if reflection will be equal to angle of incidence i.e 27 degrees.

Thus, correct option is C. 27°

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

answer:

a=9
