Answer:
Step-by-step explanation:
use the distance formula
dist = sqrt[ (x2-x1)^2 + (y2-y1)^2 ]
where point one ,P1, is A and point 2, P2, is C, so
P1 = (x1,y1) = (-7,3)
P2 =(x2,y2) = (0,6)
then
dist = sqrt[ (0 - (-7))^2 + (6-3)^2 ]
dist = sqrt [ 7^2 + 3^2 ]
dist = sqrt [49 +9 ]
dist = sqrt [58]
dist = 7.6157....
AC = 7.6 ( rounded to nearest tenth)
