1- Find the distance AB in the following cases: a- The line AB is sloped with length 543.60 m and the slope angle is 22° 15. b- The line AB is sloped with length 480.55 m and the height difference between AB is 24.35 m. c- The line AB is divided to three parts; first part is horizontal with 32.45 m; the second part is sloped with angle 12° 25 and length 55.54 m; the third part is sloped with length 132.74 m and with height difference is 14.55 m.

b- The line AB is sloped with length 480.55 m and the height difference between AB is 24.35 m.
c- The line AB is divided to three parts; first part is horizontal with 32.45 m; the second part is sloped with angle 12° 25 and length 55.54 m; the third part is sloped with length 132.74 m and with height difference is 14.55 m.
2- Explain with aid of sketch how to measure the distance AB in the following cases:
a- There is an obstruction between point A and point B.
b- There is a continuous obstruction between point A and point B.
3- 50 m tape was used to measure line SF; if the measured distance was 1288.54 m. Find the corrected distance if the true length of the tape is 49.96 m, the field temperature is 33, the standard temperature is 20, the thermal expansion coefficient is 0.00002.
4- 100 ft tape was used to measure line DF; if the correct tape length is 100.05 ft, the field temperature is 37°, the standard temperature is 20°, the thermal expansion coefficient is 0.00004, Calculate the corrected distance if the measured one is 425.50 ft.
