2. Correct the survey data below for a closed traverse. LINE OBSERVED DIMENSIONS DISTANCE BEARING (m) АВ 319.27 N 86°46' E N 1°35' W S 78°50' BC 551.35 CD 417.26 W 002 EL

Given the following tabulated data for a closed traverse, determine the bearings of CD and EA. COURSE AB BC CD DE EA LENGTH (m) 668.15 670.32 610.68 515.26 448.50 BEARING N58°32'W 348.78 S35°10'W Unknown N13°30'E +N Unknown -S 501.02 547.97 (Unknown) (Unknown) +E -W 120.29 569.89 386.08 (Unknown) (Unknown)

Given the following data for a closed traverse in which the length of sides BC and CD are unknown. For Length and Bearing of AB (795.62 m, S 03 deg 05’ W), BC (Unknown, S 52 deg 50’ W), CD (Unknown, N 12 deg 42’ W), DE (650.25 m, N 40 deg 15’ E), EA (541.55 m, S 85 deg 58’ E). If BD is chosen as the closing line, its length is • 977.23 m • 902.13 m • 853.71 m • 24.11 m • 903.48 m

A closed traverse has the following data: Line Bearing Distance (m) AB N 30deg 30min W 56.50 BC N 75deg 30min W 47.80 CD S 45deg 30min W 85.70 DA Find the area of the traverse.
