We know that sum of two complementary angles are 90°. Therefore
(i) Measure of complementary angle of 45°
= (90° – 45°) = 45°
(ii) Measure of complementary angle of 65°
= (90° – 65°) = 25°
(iii) Measure of complementary angle of 41°
= (90° – 41°) = 49°
(iv) Measure of complementary angle of 54°
= (90° – 54°) = 36°
