Answer:
zero
Step-by-step explanation:

Short Answer Only B is true.
Reasoning
A
A is not True. CBG is not equal to DBG. They are supplementary but not equal.
B
B is correct.
C
CBG = DBF are given as equal. It is not necessarily true that they are supplementary. That would be true only if they were both 90o
D
The two angles are equal, but they are not supplementary. They would be only if both were 90o which is shown not to be the case.
