2. It is required to provide horizontal control in the area covered by points t1, t12, t3,14, t5 and t6 as shown
in Figure 2 below. The extract of the reduced data from the field notebook is as follows:
Bearings:
A - P = 50° 10' 15",
tl – t2 = 84 59' 58",
t3 – 12 = 00° 00'16",
14 – 15 = 205° 00' 11",
t6 – 15 = 80°00' 15",
B- Q = 125° 36' 30"
A – tl = 135° 00' 07",
t2 – tl = 265° 00’ 00",
t3 – 14 = 86 59' 59",
t5 – 14 = 25°00' 03",
16 – B = 182° 00' 24",
tl – A = 314 59' 52",
12 – 13 = 180° 00' 13",
14 – 13 = 266° 59' 53",
