Answer:
Three collinear points
Step-by-step explanation:
AC's length has been given to us as 15 units and AB is 10 units so to find BC you will need to subtract AC from AB
so let's subtract
15-10
= 5 units
So , BC is 5 units !
option C!!!
10 BC
A-----------B--------------C
|<-----------15------------>|
10 + BC = 15
BC = 15 - 10
