(a)
see triangle FCD:
angle EFG + 90 = angle AFE
angle EFG + 90 = 2 angle BAG
angle EFG = 2 angle BAG - 90
angle FCD = angle ABC = 3 angle BAG
so
angle EFG + angle FCD + 35 = 180
2 angle BAG - 90 + 3 angle BAG + 35 = 180
5 angle BAG = 235
angle BAG = 47deg
(b)
angle EFG = 2 angle BAG - 90
angle EFG = 2 x 47 - 90 = 4deg
