Answer:
110°
Step-by-step explanation:
We are given that AD // EG
Hence ∠EFB and ∠CBF are alternate angles and hence have the same measure
therefore : m∠CBF = 35°
Recall that an exterior angle of a triangle is equal to the sum of its two remote interior angles (see attached)
hence
Exterior ∠FCD = interior angles ∠CFB + ∠CBF
∠FCD = 75° + 35°
∠FCD = 75° + 35° = 110°
