The mirror forms an image of the window that is the same height as the window and the same distance from the mirror as the window is from the building. So, the height of the window is 35.33 m - 22.85 cm = 35.10 m. Since Emanuel's eye is 2 m above the ground, the window is located 35.10 m + 2 m = 37.10 m above the ground. Rounded to the nearest unit, this is 37 m.
