From Baltazar to Balanacan, the back azimuth is which value?

Back azimuth is the direction from Balanacan to Baltazar, the line opposite to the direction from Baltazar to Balanacan. In bearings, you obtain it by taking the forward azimuth and adding 180 degrees (wrapping around if needed). If the line from Baltazar to Balanacan points roughly 9°11'50.60" (toward the north-northeast), its opposite direction—the back azimuth—would be 180° higher: 189°11'50.60". This matches the given value, since adding 180° flips the direction. Therefore, the back azimuth is 189° 11' 50.60".
