First find the component vectors in the east west direction and then in the north south direction. Find the resultant vector. 1) 5 km S 120 degrees W = 5km s 60 degrees E. Its component in the East direction is 5 cos 60 = 2.5 km 2) 10 km S 75 degrees E Its component in the East direction is 10 cos 75 = 2.59 km 3) 15 km N 85 degrees E Its component in the East direction is 15 sin 85 = 14.94 km 4) 20 km N 20 degrees E Its component in the East direction is 20 sin 20 = 6.84 km Adding all in the east direction the resultant of all these is 26.87 ======================================… 1) 5 km S 120 degrees W = 5km S 60 degrees E. Its component in the South direction is 5 sin 60 = 4.33 km 2) 10 km S 75 degrees E Its component in the south direction is 10 sin 75 = 9.66 km 3) 15 km N 85 degrees E is the same as Its component in the North direction is 15 cos 85 = 1.31 km 4) 20 km N 20 degrees E Its component in the North direction is 20 cos 20 = 18.8 km Considering south as negative sum of all
