a = 90 ̊ - 8 = 90 ̊ - 23 ̊ 26’07’’
b = 90 ̊ - 4 = 4 ̊ 11’20.35”
A= 67 ̊ 08’06.16
a = 66 ̊33’53”
b = 94 ̊17’20.35”
A = 67 ̊08’ 06.16”
Shiftan (1: 94 ̊ 17’20.35 tan 67 ̊ 08’06.16”)
Cotan P = Cos b tan A
Shiftan (1.85 ̊ 42’ 39.65” tan 67 ̊ 08’06.16”
P = 0 ̊ 16’ 54.81 ̊
1: tan 66 ̊ 33’53” x tan b 94 ̊17’s0.35” x cos 0 ̊16’ 54.31”
= 5.779754234
= 5 ̊ 46’ 47.12”
