11. Stations E, C, D are three triangulation shore signals whose positions were determined by the angle W = 146°30' (interior angle ACD). The sides EC is 1200m and the side CD is 965m. A sounding at F was taken from a boat and the angle EFC was observed to be 28 15' while angle CFD was determined to be 22°30'. Points ECDF (clockwise) formed a quadrilateral and line CF divides this quadrilateral into two triangles. Hint: Plot the four stations starting at point E. The bearing of line CE is N 30°00' E. What is the value of iangle X (interior angle CEF)? a) 85°34' 30 23' c) 78°45' 12. In item number 11, the value of Y (interior angle CDF) in nearest to 82 22 b) 65°34' c) 76°40' 13.
