The measure of BC is 26.
It is required to find Bc.
A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely.
Given that:
If b is the midpoint of AC, it means the point B divides the line segment AC in two equal parts. So, the measure of AB and the measure BC are equal to half of the measure of AC.
AB=BC
first we know that:
AB+BC=AC
So,
AB+BC=AC
It can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9
∴
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
Therefore, the measure of BC is 26.
