the lamp is 3m above the boy (4.2m - 1.2m)
the tangent of the angle of elevation from the top of the boy to the lamp
... tan(Θ) = 3m / 6m
length of shadow / boy's height = 6 / 3
the tangent of the angle of elevation from the top of the boy to the lamp
... tan(Θ) = 3m / 6m
length of shadow / boy's height = 6 / 3
