mansi shines a beam of light on a mirror. The angle between the beam and the mirror is 25°. The beam reflects off the mirror at
an angle of 25°. Find the measure of the unknown angle.
1 answer:
Answer:
130°
Step-by-step explanation:
The diagram for the question is redrawn on the attached image. It was obtained online.
Basically, what the question is asking is for the angle between the new path of the beam and the old path if the beam continued without being reflected by the mirror.
The line of the old path of the beam of light is a straight line. And the sum of angles on straight line = 180°
25° + 25° + y° = 180°
y = 180° - 50° = 130°
