A person whose eyes are 2.87 m above the floor stands 2.11 m in front of a vertical plane
mirror whose bottom edge is 41 cm above the floor. What is the horizontal distance x to the
base of the wall supporting the mirror of the nearest point on the floor that can be seen
reflected in the mirror?
Draw a good sketch and make the incident and reflected rays at the same angle to the perpendicular to the mirror at the bottom.
