Answer:

11. AW║BY

12. DX║YZ

13. AW║YZ

14. AW║DZ

Step-by-step explanation:

11. If alternate interior angles are congruent, the lines the transversal crosses are parallel.

12. The sum ∠5+∠6 is an alternate interior angle with ∠10. The reasoning of problem 11 applies.

13. If same-side interior angles are suppplementary, the lines the transversal crosses are parallel.

14. Lines perpendicular to the same line are parallel.

$~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{4}v^2\stackrel{\stackrel{b}{\downarrow }}{-16}v\stackrel{\stackrel{c}{\downarrow }}{+7}=0 \qquad \qquad v= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ v= \cfrac{ - (-16) \pm \sqrt { (-16)^2 -4(4)(7)}}{2(4)} \implies v= \cfrac{ 16 \pm \sqrt { 256 -112}}{ 8 } \\\\\\ v=\cfrac{16\pm\sqrt{144}}{8}\implies v=\cfrac{16\pm 12}{8}\implies v= \begin{cases} \frac{7}{2}\\[1em] \frac{1}{2} \end{cases}$
