Question one, how do you solve this? "A, B, and C are collinear. Find AC if AB = 12 and BC = 8"

Question two, can anyone solve these two problems i attached? They use Segment Addition and Angle Addition Postulates.

Answer:

20''

Step-by-step explanation:

If points A, B and C are collinear, then A, B and C lies on the same straight line. Hence AB+BC = AC

Given

AB = 12''

BC = 8''

To get length od segment AC, we will substitute the given values into the formula above as shown;

AB+BC = AC

12 + 8 =AC

AC = 12+ 8

AC = 20''

Hence the length of AC is 20''
