Answer:
The answer to your question is:
12) C
13) AT = 29
Step-by-step explanation:
12)
Data
A (6, -3)
B (-6, 19)
midx = (x1 + x2) / 2 midy = (y1 ´y2) / 2
midx = ( 6 - 6) / 2 midy = (-3 + 19) / 2
midx = 0 / 2 midy = 16 / 2
midx = 0 midy = 8
mid point = (0, 8)
13)
As A is the midpoint of CT then CA = AT
2x - 19 = x + 5
2x - x = 19 + 5
x = 24
AT = 24 + 5
AT = 29
