Figure 7-45.—Level net for use in answering question Q4. Q4. Q5. Q6. Refer to the level circuit ABCA shown in figure 7-45.  What  is  (a)  the  error  of  closure  in  the circuit,   and   (b)   the   corrected   difference   in elevation (cycle I) for line AB? What is the latitude of a 300-foot traverse line running due east and west? Assume that you are working with a traverse that has a total length of 2,541.35 feet, an error of closure in latitude of –1.73 feet, and an error of closure in departure of +2.01 feet. What is the ratio of error of closure? Q7.   Compute the bearing of traverse line AB when the coordinates of station A and B are follows: Station A: X = 627.42, Y= 326.87 Station B: X = 864.81, Y= 542.50 Q8.   Refer to figure 7-46. What is the approximate area  contained  within  the  traverse? Figure 7-46.—Closed traverse for use with question Q8. 7-30
