The diagram shows an cd and ge which statement can be proven true from the diagram

option B., which states ∠ DGB is supplementary to ∠ CGB.

Explanation:

The question is incomplete.

Herewith, I attach the image with the diagram and the full question.

1) In the diagram you find that the ∠ DGB and ∠ CGB lie in the same plane and they form a straight ray.

2) That proves that they add up 180°.

2) The definition of supplementary angles is that they add up 180°. Then, it has been proved that they are supplementary angles.

3) Hence the answer is the option B. which states ∠ DGB is supplementary to ∠ CGB.
