Omitted measurement: the missing bearing and distance of one side
Four sides of a five-sided parcel are recovered but the fifth runs through a swamp. Both its bearing and its length are computed from the condition that the traverse must close.

Given
A five-sided parcel A-B-C-D-E-A. Four sides were measured; the fifth, E-A, crosses standing water and could not be measured.
A-B N 62°15′00″ E 425.60 ft
B-C S 27°40′00″ E 316.85 ft
C-D S 55°10′00″ W 388.20 ft
D-E N 78°30′00″ W 254.75 ft
E-A bearing and distance both unknown.
The four measured courses are taken as correct; the whole of any error will fall into the computed course.
Distances to 0.01 ft, bearings to 1 second.
Required
The latitude and departure of the missing course.
Its bearing and its length.
The coordinates of every corner on an assumed grid with A at N 1000.00, E 1000.00.
