how to find vertical dimension of the mirror

suppose a person is standing x cm from the mirror

and the angle of depression from his eyes to bottom of the mirror is theta 1

angle of elevation from his eyes to top of the mirror is theta 2

so , vertical dimension is given by

h1 = x tan theta 1

h2 = x tan theta 2

vertical dimension = h1 + h2

= x ( tan theta 1 + theta 2 )
