Answer» Answer: Q3 (a) Complementary ANGLES are angles that add up to 90° angle that is complement of itself is 45°. This because when you add 45° to itself, it will give you 90° (B) Supplementary angles are angles which add up to 180°. The angle which is a supplement to itself is a right angle, or a 90° angle. Step-by-step explanation: Q4 : Two angles whose sum is 90° are called complementary angles. Complement of 42° = 90° − 42° = 48° Complement of 21° = 90° - 21° = 69° Complement of 27° = 90° - 27° = 63° Complement of 70° = 90° - 70° = 20° Q5 Two angles whose sum is 180° are called supplementary angles. Supplement of 128° = 180° − 128° = 52° Supplement of 24° = 180° − 24° = 156° Supplement of 118° = 180° − 118° = 62° Supplement of 92° = 180° − 92° = 88° Supplement of 42° = 180° − 136° = 44° |
