(2) The point m will fall between Z and Q when d and L are of the same name,if /<90° and L>&. Hence (fig. 2) Z>90°; M = a-/3; and C = 90°-B = (90°-6)-(90°-L)=L-6. … (3) Tlie point m will fall between P and N when d and L are of the same name,if 0 90° (and then the tables must be entered with 180°-<, instead of t). Henc€(fig. 3)Z<90°; M = /3-a; and C = 90°-B = (90°-L) + (90°-&) = 180°-(L + 6). ALTITUDE AND AZIMUTH TABLES. [Page 189
