A + B + C +D=0 N C = 3.02 km D = ? km C W E 0 = ? 170 _0-- D S 16 X 7.50 B B = 2.48 km A = 4.40 km A He then correctly calculates the length in kilometers and orientation in degrees west of south of the fourth side D. What is his result in kilometers and degrees west of south? D = km west of south + Additional Materials Reading
