Which part of the proof does the fourth statement and reason represent? given: ab ≅ bc bc ≅ ef prove: eg = ab + fg it is part of the given information. it is part of the argument. it is the conclusion. it is an assumption.

B, it is an argument

Step-by-step explanation:

Option B is correct.

Reason:It is an argument

Step-by-step explanation:

Given:  and

By transitive property:  a = b  and b = c then, a =c

⇒

AB = EF                                [def of segment]

By Segment Addition Postulate states that given  two points A and C, and a third point B lies on the line segment AC if and only if the distances between the  points satisfy the equation

AB + BC = AC.

Since, the line segment EG , F lies on the line segment;

then, by segment addition postulates we have;

EG = EF + FG

By substitution AB=EF

⇒ EG = AB + FG                     hence proved!

Since, in the fourth statement reason is:  It is an argument

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
