The observed lengths of the sides (in feet) of a five-sided closed polygon traverse are as follows:

AB=202.74, BC=243.87, CD=498.37, DE=306.33, and EA=390.78. (Note: Assume units of feet for all distances.)

The preliminary azimuths obtained after balancing the angles are as follows:

AB=218∘59′30′′, BC=147∘45′49′′, CD=75∘05′27′′, DE=336∘56′04′′, EA=266∘12′23′′.
