Tangent (theta) = (opposite/adjacent) = (1/8")/146" = .000856
Arctan .000856 = 0.000855999791 rad

Tan (0.000855999791 rad) = Z/120"
Z = Tan (0.000855999791 rad) x 120"
Z = 0.000856 x 120"
Z = .103" (rounded)

So I guess you're assuming that the line ABC runs vertically, not horizontally as your diagram shows changing the movement of B to up not left. Right?
