Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.
3)

The definition of supplementary angles is that two angles are supplementary if their measures sum to
180
∘
.
4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.
5)

Subtracting

from each side of 4. gives us the above result.
6) Definition of right angle

38/14= 2 10/14= 2 5/7
The answer is 2 5/7
Keisha is correct, because as per the definition <u>A function is a special relationship where each input has a single output</u>.
A function is a special relation. In other words, a relation if and only if it has a specific characteristic where each input has a single output, then it is called a Function.
All functions are relations but not all relations are functions.
