Answers
Given : angles. (i) 70° (ii) 45° (iii) 40°0 (iv) 60°
To find : complementary angles
Solution:
Complementary angles are angle pairs whose measures sum to one right angle (1/4 turn, 90°, or π/2 radians).
complementary angles of 70° = 20°
complementary angles of 45° = 45°
complementary angles of 40° = 50°
complementary angles of 60° = 30°
supplementary angles forms a linear pair means sum = 180°
supplementary angle of 100° = 80°
supplementary angle of 90° = 90°
supplementary angle of 60° = 120°
supplementary angle of 30° = 150°
∠AOC & ∠BOC forming a linear pair.
∠AOD & ∠BOD forming a linear pair.
∠AOC + ∠BOC = 180°
∠AOD + ∠BOD = 180°
