A person standing d = 141 centimeters from a mirror notices that the angle of depression from his eyes to the bottom of the mirror is a = 14°,
while the angle of elevation to the top of the mirror is b = 14°.
Find the vertical dimension of the mirror. (Round your answer to the nearest whole number.)
_______cm
---------------
b = bottom half of mirror, below eye level
tan(14) = b/141
------
The top half is the same.
Length of the mirror = 2b
