Question

Find the complement of each of the following angles:

(i) 55°

(ii) 16°

(iii) 90°

(iv) 2/3 of a right angle

Answer 1

(i) We know that the complement of 55° can be written as

55° = 90° – 55° = 35°

(ii) We know that the complement of 16° can be written as

16° = 90° – 16° = 74°

(iii) We know that the complement of 90° can be written as

90° = 90° – 90° = 0°

(iv) We know that 2/3 of a right angle can be written as 2/3 × 90° = 60°

60° = 90° – 60° = 30°
