answer : 48 degrees
method
1. opposite angles are the same , so CFG os the same as GAC - these two added up are 132 + 132 = 264
2. angles add up to 360 in a quadrilateral , so the sum of the two remaining angles is 360 - 264 = 96
3. because the two remaining angles , ACF and FGA , are opposite , those are equal too. so u just half to get one of them : 96 / 2 = 48
