Question

Find the complement of each of the following angles:

(i) ${55}^{\circ }$

(ii) ${16}^{\circ }$

(iii) ${90}^{\circ }$

(iv) $\frac{2}{3}$ of a right angle

Answer 1

(i) Complement of 55° = (90 -55)° = 35°

(ii) Complement of 16° = (90 – 16)° = 74°

(iii) Complement of 90° = (90 – 90)° = 0

(iv) $\frac{2}{3}$ of a right angle = $(90\times \frac{2}{3})$°=60°

Complement of $\frac{2}{3}$ of a right angle = (90 – 60)° = 30°
