Question

1. b is the midpoint of line segment ac. if ab = x+2 and bc = 30, find the value of x. be sure to include your work.(3 pts)

Explanation:

Step1: Use mid - point property

Since B is the mid - point of AC, then AB = BC.
So, $x + 2=30$.

Step2: Solve for x

Subtract 2 from both sides of the equation: $x=30 - 2$.

Answer:

$x = 28$
