Final answer:
Two obtuse angles cannot be complementary to each other as an obtuse angle is more than 90 degrees and by definition, complementary angles add up to 90 degrees.
Step-by-step explanation:
No, two obtuse angles cannot be complementary to each other. In mathematics, complementary angles are defined as two angles whose measures add up to 90 degrees. An obtuse angle is defined as an angle that is more than 90 degrees and less than 180 degrees. Hence by definition, if one angle is obtuse (more than 90) it is impossible for the two to add up to 90 degrees, thus two obtuse angles cannot be complementary.
