I clearly don't know how to do it if i did i wouldn't be asking for help.

132 degrees

Step-by-step explanation:

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

x = 3 ± √(5+y)

8 < i think

hope this !
