D) This information cannot be gathered from the hypothesis, conclusion, or the diagram.
We know ∠1 + ∠2 measures to 180 degrees. This means they are supplementary, because supplementary angles add up to 180°.
But we know this because of the statement, which states the sum of ∠1 and ∠2 is 180 degrees.
So the information was from the statement, not the hypothesis, conclusion, or diagram.
You can't look at a diagram to find exact measurements, because most of them are not to scale or not an accurate representation of the measurements.
There was no hypothesis, which is a proposition that hasn't been verified or proven to be false.
There was no conclusion, which is something that was proven or found out during an experiment or test.
