Write the complement of each of the following angles: (i) 20° (ii) 35° (iii) 90° (iv) 77° (v) 30°

(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°)

(i) Given angle is 20°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 20° = 70°

(ii) Given angle is 35°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 35° = 55°

(iii) Given angle is 90°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 90° = 0°

(iv) Given angle is 77°

Since the sum of an angle and its compliment is 90 

Therefore, its compliment will be:

90° – 77° = 13°

(v) Given angle is 30°

Since the sum of an angle and its compliment is 90°

Therefore, its compliment will be:

90° – 30° = 60°
