Question

Write the complement of each of the following angles: (i) 20&#xB0; (ii) 35&#xB0; (iii) 90&#xB0; (iv) 77&#xB0; (v) 30&#xB0;

Philoid · Accepted Answer

(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
