$(2$ points$)$ Given the traverse observations, shown on pages $3$ and $4,$ for a $6-$sided closed polygon

traverse. Complete the following:

a$.$ Determine the mean angle, in the direct face, for each set of observations. $($Recall that one

set includes a direct and reverse face measurement$).$

b$.$ Determine the sum of observed interior angles for this traverse. Be sure to also report each

individual interior angle.

c$.$ What is the angular misclosure of this traverse?

d$.$ What FGCS standard would the misclosure meet, based on the Federal Geodetic Control

Committee, $1984$: Standards and Specifications for Geodetic Control Networks?
