Write the complement of each of the following angles:

(i) 20° (ii) 35° (iii) 90°

(iv) 77° (v) 30°

(i) Given angle is 20^o

Since the sum of an angle and its compliment is 90^o

Therefore, its compliment will be:

90^o – 20^o = 70^o

(ii) Given angle is 35^o

Since the sum of an angle and its compliment is 90^o

Therefore, its compliment will be:

90^o – 35^o = 55^o

(iii) Given angle is 90^o

Since the sum of an angle and its compliment is 90^o

Therefore, its compliment will be:

90^o – 90^o = 0^o

(iv) Given angle is 77^o

Since the sum of an angle and its compliment is 90^o

Therefore, its compliment will be:

90^o – 77^o = 13^o

(v) Given angle is 30^o

Since the sum of an angle and its compliment is 90^o

Therefore, its compliment will be:

90^o – 30^o = 60^o
