B is the midpoint of AC. If AB = x +5 and BC = 2x - 11, find the measure of AB.

AB=21

Step-by-step explanation:

B is the midpoint of AC, the AB=BC

AB=x+5, BC=2x - 11

x+5=2x-11

x-2x=-11-5

-x=-16, then

x=16

AB=x+5=16+5=21

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.
