Answer:
(C)26 units
Step-by-step explanation:
Since point B bisects AC into two equal parts
AB=BC
Since the two right triangles have side BD in common, we can then say that the two triangles are congruent and the length of the hypotenuses (AD and DC) are equal.
If AD=DC
8x-1=6x+9
8x-6x=9+1
2x=10
x=5
Now,
AB=3x-2
=3(5)-2
=13 Units
Since AB=BC
AC=AB+BC
=13+13
AC=26 units
The measure of AC is 26 units.
