Use Segment Addition Postulate to write and equation and solve for x.

• x = 3

• x = 2

• x = 6

• x = 5

Answer explanation

Segment Addition Postulate

PQ + QR = PR

6 + 2x - 2 = 3x + 2

2x + 4 = 3x + 2

-1x = -2

x = 2

Using the Segment Addition postulate, which is the correct equation relating the segments?

• AM + MB = AMB

• AB + AM = MB

• AM + MB = AB

• A + B = AMB

What is the length of YZ?

type the just the number.

Mathematical Equivalence

ON

Answer explanation

Using Segment Addition Postulate

XY +YZ = XZ

51 + YZ = 88

YZ = 88- 51

YZ = 37

Suppose AC =  48, find the length of AB.

Mathematical Equivalence

ON

Answer explanation

Use Segment Addition Postulage

AB + Bc = AC

2x - 4 + 3x + 2 = 48

5x - 2 = 48

5x = 50

x = 10

Then substitute x = 10 into the expression for AB

AB = 2(10) - 4 = 16

AB = 16
