I have been trying to solve this problem using many equations, but am not getting the right answer. I guess I'm not using the right formula because I don't know it. Can someone please help.
The rear window in a car is approximately a rectangle, 1.17 m wide and 0.160 m high. The inside rear-view mirror is 0.600 m from the driver's eyes, and 1.23 m from the rear window. What is the minimum height of the rear-view mirror if the driver is to be able to see the entire height of the rear window in the mirror without moving her head?
do: 1.23m
di: 0.600m
ho: 0.160m
hi: ?
hi = (di/do)ho = (0.600/1.23)0.160m = 0.0780m
