Question

Write the complement of each of the following angles:

(i) 20°

(ii) 35°

(iii) 90°

(iv) 77°

(v) 30°

Answer 1

(i) Let the complement of angle measures x°

Since the angles are complementary, therefore their sum must be equal to

Or we can say that

Hence, the complement of angle measures

(ii) Let the complement of angle measures x°

Since the angles are complementary, therefore their sum must be equal to

Or we can say that

Hence, the complement of angle measures

(iii) Let the complement of angle measures x°

Since the angles are complementary, therefore their sum must be equal to

Or we can say that

Hence, the complement of angle measures

(iv) Let the complement of angle measures x°

Since the angles are complementary, therefore their sum must be equal to

Or we can say that

Hence, the complement of angle measures

(v) Let the complement of angle measures x°

Since the angles are complementary, therefore their sum must be equal to

Or we can say that

Hence, the complement of angle measures.
