(i) Given angle is 20°

Since, the sum of an angle and its complement is 90° .

its, complement will be (90° - 20 = 70°)

(ii) Given angle is 35°

Since, the sum of an angle and its complement is 90° .

its, complements will be (90° - 35° = 55°)

(iii) The given angle is 90°

Since, the sum of an angle and its complement is 90° .

its, complement will be (90° - 90°  = 0)

(iv) The given angle is 77°

Since, the sum of an angle and its complement is 90° .

its, complement will be (90° - 77° = 13)

(v) The given angle is 30° .

Since, the sum of an angle and its complement is 90° .

its, complement will be (90° - 30° = 60°)
