Final answer:
Without a diagram, it's difficult to answer your question precisely. But, in general, supplementary angles add up to 180 degrees. So, to find an angle supplementary to ∠DOC, you need to find an angle that adds up with ∠DOC to equal 180 degrees.
Explanation:
Unfortunately, it is impossible to answer your question definitively without the diagram referred to in your question. However, in general terms, if you are looking for an angle that is supplementary to ∠DOC, you need to identify the angle that, when added to ∠DOC, totals 180°, as supplementary angles share this characteristic. For example, if ∠DOC is 120°, the supplementary angle would be 60°, because 120° + 60° equals 180°.
