Two acute angles can be only complementary, as they add up to 90°. Learn how to define angle relationships. (ii) Two acute angles can form a linear pair. d. False; they must be vertical angles. Two supplementary angles are always obtuse angles. Find their measures. So we can also say that angles DBA and angles ABC are complementary. Therefore, Acute angle + Acture angle < 90° + 90° < 180° Thus, the two acute angles cannot be supplementary angles. No, since obtuse angles must be greater than 90 degrees and less than 180 degree, any two obtuse angles would add up to greater than 180 degrees. A supplementary angle can be composed of one a cute angle and another obtuse angle. If 3 times the supplement of an angle is subtracted from 7 times the complement of the angle,...
