I only need $12\mathrm{.}2.$

In Problems $12\mathrm{.}1$ to $12\mathrm{.}4,$ compute the latitudes and departures for the sides of the traverses shown in the accompanying figures. Determine the error of closure and precision for each of the traverses.

$12\mathrm{.}1($Ans$.$: $E_C=0\mathrm{.}069ft,$ precision $=\frac{1}{24},589)$

$12\mathrm{.}2$
