You hold a small plane mirror 0.50 m in front of your eyes, as shown in the figure. The mirror is 0.32 m (h) high, and in it you see the image of a tall building behind you. The building is93 m (D) behind you. Suppose the person's eyes are 1.6 m above the ground and that the small plane mirror can be moved up or down.

(a) Find the height of the bottom of the mirror such that the lowest point the person can see on the building is 22.9 m above the ground.

(b) With the mirror held at the height found in part (a), what is the highest point on the building the person can see?
