Answer: line N
Lenght of XY: 3
Step-by-step explanation:
The line N splits <u>XY</u> into two parts

-9x on each side
-4x+8=12
-8 on each side
-4x=4
divide by -4 on each side
x=-1

Answer: SSS Postulate</h3>
The tickmarks tell us which pairs of sides are the same length.
- AB = BC due to the single tickmarks
- AD = CD due to the double tickmarks
So far we have two pairs of congruent sides.
The third pair of congruent sides are the overlapping or shared sides BD = BD which is true by the reflexive property (anything is congruent to itself).
Overall we have three pairs of congruent sides allowing us to use SSS. Each "S" stands for "Side".
Math is not exactly my strongest link, but I would say the answer to this would be C
