If two angles are complementary, the sum of their measures is 90 degrees. Call one of the angles x. This means that its complement is 90 - x degrees. But the difference in their measures is 12 degrees.
For this case we have the following expression:

Let's evaluate the expression for some values of x.
We have then:
For x = 1:

For x = 2:

For x = 3:

For x = 4:

For x = 5:

Answer:
The value of the expression in ordered pairs is:
- (1,8)
- (2.6)
- (3,4)
- (4.2)
- (5.0)
Since "chair" probably means "share", John will have 2 2/3 slices of pizza left.
The 12 slice pizza is split between 3 people, so each person gets 4 slices. John only eats 2/3 of his 4 slices, and 2/3 of 4 is 2 2/3.
You can't use AAA to prove two triangles congruent because triangles can have the same measures of all its angles but be bigger or smaller, AAA could probably <span>be used to prove two triangles are similar not congruent.</span>
