Question

use the segment addition postulate to find X and the length of AC if AB = 5, BC = 2X + 6, and AC = X + 10

X =

AC =​

Answer 1

Answer:

x = -1

ac = 9

Step-by-step explanation:

5 + 2x + 6 = x + 10

2x - x = 10 - 5 - 6

x = -1

ac= 5 + 2 (-1) + 6 = 5 - 2 + 6

= 9

Answer 2

Answer:

x = -1 AC = 9

Step-by-step explanation:

x+10 = 5 + 2x+6

x+10 = 2x+11

-x = 1

x = -1

AC = ×+10 = (-1)+10= 9

5+2(-1)+6 = 9
