3-12 The angles shown in Fig. 3-15 are measured: a, = 40°00'00", a; = 100°00'30", a, = 50°00'20", a.= 120°00'00", a, = 40°00'20". All measurements are uncorre- lated and have the same precision. The angle at A is held fixed at 90°00'00". Adjust the measured angles ding to the principle of least squares. B as a 3 A D Fig. 3-15.
