To determine which pairs of angles are complementary (adding up to 90 degrees), we need the measures of the angles involved. However, since the specifics are not provided, generally speaking, if you have specific angles like ∠1, ∠2, ∠3, ∠4, and ∠5, you can evaluate pairs by checking their measures.
If you can provide the measures of any of these angles, I can help identify which pairs are complementary. Otherwise, if you are simply looking at angle pairs without measures, it's hard to determine their relationships.
