BEGINNING+INTERMEDIATE ALGEBRA 18WK COD, Chapter G, Problem 1E , additional homework tip  1

If the sum of the two angles is 90o then the angles are known as complementary angles.

Supplementary angles:

If the sum of the two angles is 180o then the angles are known as supplementary angles.

BEGINNING+INTERMEDIATE ALGEBRA 18WK COD, Chapter G, Problem 1E , additional homework tip  2

Calculation:

Two angles are complementary if the sum of their measures is 90o.

The complement of a 19o angle is 90o-19o=71o.

Check:

19o+71o=90o

Conclusion:

Therefore, the complement of a 19o angle is 71o.
