Answer:
D and C
Step-by-step explanation:
I don't really know if my answers are even correct but I did some research on them. I don't want to waste your time --or mine.
Answer:
it is a because you subtract the ten from both side and that makes the -8 into a -18 then you divide by 3 and your answer is -6
If sides are congruent then the angles ACROSS from them are also congruent.
Since WV and VU are congruent, angle U is congruent to angle W.
Set up an equation and solve.
See attachment.
x = 8
Angle w = 63
You're answer will be C 13x2+12xy+9y2
