Answer:
A x=4
B dont know
C x=-14
1. x=1
2. x= 
Step-by-step explanation:
The answer to this is 1/2 of a meter long.
Vertical angles= XAW and UAY
complementary angles =XAW and XAZ
adjacent but not complementary or supplementary = XAZ and ZAY
supplementary = XAW and WAU
I think you forgot to include that T is the midpoint of SV, but what this would mean is that ST = TV.
5x + 2 = 3x + 12
Subtract 2 from both sides.
5x = 3x + 10
Subtract 3x from both sides.
2x = 10
Divide both sides by 2.
x = 5
Now plug that x into ST.
ST = 5(5) + 2
ST = 25 + 2
ST = 27
