PLEASE HELP i will give you the brainliest!! Only answer if you know or if you know some of it anything helps!
In a word processing document or on a separate piece of paper, use the guide to construct a two column proof proving AC > EF given BC = EF. Upload the entire proof below.
Given:
BC = EF
Prove:
AC > EF

According to the question, we are to complete a 2-column proof to show that the measure of BC is equal to EF:

Given the following:

BC = EF

Let BC = EF = x

AC = AB + BC 1

AC = AB + x 2

From equation 2, AB = AC - x 3

Substitute equation 3 into 1:

AC = AB + BC

AC = AC-x + BC

AC-AC = -c + BC

0 = -x + BC

BC = x

Since AC is greater than AB by a value of x, hence AC > BC
