Answer:
115°
Step-by-step explanation:
● DAG is equal to 180°
● DAG = DAH + HAG
● HAG IS 130°
● DAG = DAH + 130° => DAH + 130° = 180°
● DAH = 180° - 130° = 50 °

ADH is a triangle
● ADH + DHA + HAD = 180°
● ADH + DHA + 50° = 180°
DHA shares the same vertex with CHE. They are opposite angles so they have the same size (35°)
● ADH + 35° + 50° = 180°
● ADH + 85° = 180°
● ADH = 180° - 85°
● ADH = 95°

BDA equals 180°
● BDA = 180°
● BDH + ADH = 180°
● BDH + 95° = 180°
● BDH = 180° -95°
● BDH = 85°
■■■■■■■■■■■■■■■■■■■■■■■■■■
BDE is a traingle
● BDH+ DEB + EBD = 180°
● 85° + DEB + 30° = 180°
● DEB + 115° = 180°
● DEB = 180° - 115°
● DEB = 65°
■■■■■■■■■■■■■■■■■■■■■■■■■■
CEF equals 180°
● CEF = 180°
● DEB + x° = 180°
● 65° + x° = 180°
● x° = 180° - 65°
● x° = 115°
