Question

point a is the midpoint of side xz and point b is the midpoint of side yz. what is ax? 2 units 4 units 6 units 8 units

Explanation:

Step1: Apply midline theorem

AB = $\frac{1}{2}$XY → $x+1=\frac{1}{2}(5x-7)$

Step2: Solve for x

Multiply both sides by 2: $2x+2=5x-7$ → $3x=9$ → $x=3$

Step3: Calculate AX

AX = $2x-2$ → $2(3)-2=4$

Answer:

B. 4 units
