Figure 7-45.—Level net for use in answering question Q4.Q4.Q5.Q6.Refer to the level circuit ABCA shown in figure7-45. What is (a) the error of closure in thecircuit, and (b) the corrected difference inelevation (cycle I) for line AB?What is the latitude of a 300-foot traverse linerunning due east and west?Assume that you are working with a traverse thathas a total length of 2,541.35 feet, an error ofclosure in latitude of –1.73 feet, and an error ofclosure in departure of +2.01 feet. What is theratio of error of closure?Q7. Compute the bearing of traverse line AB whenthe coordinates of station A and B are follows:Station A: X = 627.42, Y= 326.87Station B: X = 864.81, Y= 542.50Q8. Refer to figure 7-46. What is the approximatearea contained within the traverse?Figure 7-46.—Closed traverse for use with question Q8.7-30
