Answer:
If A'B'C' is the image of ABC in the mirror, then the distance between the object (ABC) and its mirror is equal to the distance between A'B'C' and the mirror.
Let's call the distance between A'B'C' and the mirror "d". According to the problem, we know that:
d = 80 cm
However, we need to find the distance between ABC and its mirror, which we can call "x". We know that:
x + d = 2x
Simplifying this equation, we get:
d = x
Substituting the value of "d" from the first equation, we get:
x = 80 cm
Therefore, the distance between the object (ABC) and its mirror is also 80 cm, which is the same as the distance between A'B'C' and the mirror.
