A survey of a triangular lot has the following data: AZAC = 78°03′22″, AZAB = 48°33′07″ and the interior angles of the triangle are: ABC = 33°52′35″, and ACB = 116°37′10″,respectively. compute the azimith AZBC ?

For the rule of 78, for a 12-month period, the last term in the sequence is 12 and the series sums to 78. for an 10 month period, the last term is and the series sum is . for a 15 month period, the last term is and the series sum is . for a 20 month period, the last term is and the series sum is
