Pot is performing Double Meridian Distance Method in order to compute the area of the traverse. Midway in his work, his nephew Ashton accidentally spilled Engr. Pots' coffee onto the notes. Engr. Pot decided to rewrite the data, only to find out that the DMD of the lines CD and DE are unreadable. He figures that he can just solve for the missing data knowing that the DMD of line DE is twice the DMD of the previous line CD. If the departure of line CD is -124.25 and that of line DE is 301.965, determine the DMD of line DE. Your answer A lot has a frontage along a road. The 2 II
