The bottom of the mirror must be halfway up t, so the angles to and from the mirror are equal
Let the bottom edge of a rectangular mirror on a vertical wall be parallel to and h feet above the level floor. If a person with eyes t feet above the floor is standing direct at a distance d feet from the mirror, what is the relationship among h,d and t if the person can just see his own feet in the mirror?
Choose one answer.
a. t=4d and h does not matter.
b. h^2 + d^2 = (t^2)/4
c. t - h = d
d. (t - h) = 4d
e. t=2h and d does not matter.
