Part 1….Question 1: Compute the angle AED in the problem below: – The angle AED is [blank1] deg, [blank2] min, and [blank3] sec. _________________________________________________________________________________________________________ Problem: The tract of land ABCDEA is to be divided into two parts by a line from point A so that the area of the southern part of the tract is 20% of the total tract area. Using the information below it is required to find the coordinates of point P required to establish the partition line AP. Total tract area = 2884882.89 m2 NOTE: YOU ARE PROVIDED THE TOTAL AREA OF THE TRACT AND THE LENGTH AND AZIMUTH OF EACH SIDE. PLEASE USE THIS INFORMATION TO SAVE EXAM TIME.    Pt X(m) Y(m) A 1406.45 1325.03 B 2561.70 2300.54 C 3530.34 1772.20 D 3391.96 561.07 E 1943.08 260.32   Side Length(m) Az (o ‘ “) AB 1512.03 049  49  19 BC 1103.36 118  36  37 CD 1219.01 186  31  05 DE 1479.77 258  16  24 EA 1192.30 333  15  05
