8.
[tex] 1 \frac{11}{16} \: inches[/tex]
9. XY is 8 and YZ is 16 because x = 4:
2x + 4x = 24
6x = 24
x = 4
XY: 2(4) = 8
YZ: 4(4) = 16
10. The total length of TG is 14cm because 10(TA) + 4(TG) = 14
11. Segment AB is equal to Segment CD because they are both 15cm. Segment AC is equal to Segment BD because they are both 8cm.
12. Draw two parallel lines and label one as q and the other as p I'm not too sure about the collinear points but I would guess they'd be at the ends of line p? Don't take my word for this one. I also don't think the fact it's on plane D is necessary information.
