Answer» (i) 140°, 40° Sum of angles = 140° + 40° = 180° ∴ These are supplementary angles. (ii) 170°, 10° Sum of angles = 170° + 10° = 180° ∴ These are supplementary angles. (iii) 75°, 15° Sum of angles = 75° + 15° = 90° ∴ These are complementary angles. (iv) 33°, 57° Sum of angles = 33° + 57° = 90° ∴ These are complementary angles. (v) 115°, 65° Sum of angles = 115° + 65° – 180° ∴ These are supplemental angles. (vi) 25°, 65° Sum of angles = 25° + 65° = 90° ∴ It is complementary angles. |
