The angle measure of ACB is 9 degrees
Answer: Option B
<u>Step-by-step explanation:</u>
To find the solution to the given problem, first we need to look into the point B. It consists two angles and both of them are on a straight angle. So, this means that the sum of angle ABC and CBD is 180 degrees, that is

We know that
. Therefore


Now, in the triangle ABC, we know that all three angles must sum 180 degrees,



Therefore, the angle ACB is 9 degrees.
