Answer:
x = 7/ 9
Step-by-step explanation:
Let x = 0.777777777777 ... ... ... ... ...........(A)
then 10 x = 7.7777777777777 ... ... ... ... ............(B)
Subtracting (A) from (B)
9 x = 7 and x = 7 /9

7 over 9 so 7/9
-8,-7
I think
AC = 12 units.
Δ ACD is right-angled. ( as CD ⊥ AB).
cos 45° = CD / AC = 6√2 / AC
AC = 6√2 / cos 45°
AC = 6√2 / 1 /√2
= 6√2 *√2
= 6 * 2
= 12 (answer)
