Write the complement of each of the following angles: (i) `20^0` (ii) `35^0` (iii) `90^0` (iv) `77^0` (v) `30^0`

Explanation

(i) The sum of an angle and its complement = `90^@`
Therefore, the complement of `20^@ = 90^@ – 20^@ = 70^@`
(ii) The sum of an angle and its complement = `90^@`
Therefore, the complement of `35^@ = 90^@ – 35^@= 55^@`
(iii) The sum of an angle and its complement = `90^@`
Therefore, the complement of `90^@ = 90^@– 90^@ =0@`
(iv) The sum of an angle and its complement = `90^@`
Therefore, the complement of `77^@ = 90^@ – 77^@ = 13 ^@ `
(v) The sum of an angle and its complement = `90 ^@`
Therefore, the complement of `30^@ = 90^@– 30^@ = 60^@`
