Question

Given a Segment AB find the midpoint; B = 30 and A = 10

Answer 1

The midpoint is at 20

Explanation:

The midpoint of a segment

Given a segment in the number line with endpoints A(xa) and B(xb).

The midpoint coordinate is calculated as follows:

`\displaystyle xm=(xa+xb)/(2)`

We are given the coordinates xa=10 and xb=30, thus the coordinate xm of the midpoint M is at:

`\displaystyle xm=(10+30)/(2)`

`\displaystyle xm=(40)/(2)`

xm = 20

The midpoint is at 20
