## Answers ( )

Step-by-step explanation:The sum of measure of complementary angles is 90° …

1) complement of 20°=90° – 20° = 70°

2) complement of 63°=90° – 63°= 27°

3) complement of 57° =90° – 57°= 33°

Answer:The sum of the measure of complementary angles is 90°.

(i) Complement of 20° = 90° – 20° = 70°

(ii) Complement of 63° = 90° – 63° = 27°

(iii) Complement of 57° = 90° – 57° = 33°
