If CD is free from local attraction then FB of DE should also be free of local attraction.. so when you calculated it should be 230degree 10 minutes. Why did it come 230degree 5 minutes?
Sir I have a doubt can u please help me Station C and station D not effected by local attractions so back bearing of BC and Forbearing of DE donot change ??
This is another method, see the title. You are trying to solve it by previous method. Here we close the traverse first by fixing the interior angles and then find the bearings of lines using those angles and previous bearings.
