Answer:
AC = 12 units.
Explanation:
Given : A triangle ABC with BD is the perpendicular bisector of AC.
To find : What is the length of AC.
Solution : We have given triangle ABC with BD is the perpendicular bisector of AC.
Bisector : Which cut the line equally in to two part.
So , BD cut AC in two equal part AD = DC.
We can write
AC = AD + DC.
Plug the values DC = 6 , AD =DC = 6.
AC = 6 + 6
AC = 12 units.
Therefore , AC = 12 units.
