There is a simple solution to this. Major arc XZ = 220° Since all circles = 360° then Minor arc XZ = 140°
**************************************************************** Perhaps they want you to use the method in the attachment. angle y = 1/2 (Major Arc XZ - Minor Arc XZ) angle y = .5 * Major Arc XZ -.5 * Minor Arc XZ .5 * Minor Arc XZ = .5 * Major Arc XZ - angle y .5 * Minor Arc XZ = (.5 * 220) -40 .5 * Minor Arc XZ = 110 -40 .5 * Minor Arc XZ = 70 Minor Arc XZ = 140
