Question:
Write the complement of each of the following angles:
(i) 20°
(ii) 35°
(iii) 90°
(iv) 77°
(v) 30°
Solution:
(i) Given angle is 20
Since, the sum of an angle and its compliment is 90
Hence, its compliment will be (90 - 20 = 70)
(ii) Given angle is 35
Since, the sum of an angle and its compliment is 90
Hence, its compliment will be (90 - 35 = 55)
(iii) Given angle is 90
Since, the sum of an angle and its compliment is 90
Hence, its compliment will be (90 - 90 = 0)
(iv) Given angle is 77
Since, the sum of an angle and its compliment is 90
Hence, its compliment will be (90 - 77 = 13)
(v) Given angle is 30
Since, the sum of an angle and its compliment is 90
Hence, its compliment will be (90 - 30 = 60)
