(Originais Teachy 2024) - Question Easy of Physics

An observer is 2 meters away from a flat mirror and wants to measure the height of an object behind him, 3 meters away from the mirror. (1) Explain how the concept of symmetry and the principle of angle of incidence being equal to the angle of reflection help the observer determine the height of the object without needing to move from his position. (2) Calculate the perpendicular distance from the object to the mirror and the distance from the image to the mirror after reflection, and justify why these distances are equal according to the laws of optics.
