1) Substitution from definition.
2) We use 
3) We are changing the order of 3 and
.
4) We add 1 and 3
and we get 
5) Substitution from definition (but the other way than at the beginning).
Given:
The pairs of angles are:
36°,24°
18°,72°
96°,84°
To find:
Whether each pair of angle measurements are complementary, supplementary or neither.
Solution:
Two angles are complementary if there sum is 90 degrees.
Two angles are supplementary if there sum is 180 degrees.
For 36° and 24°,

So, this pair is neither complementary not supplementary.
For 18° and 72°,

So, this pair is complementary.
For 96° and 84°,

So, this pair is supplementary.
