Answer:
= 9
Step-by-step explanation:
There are two angles given.
One is 90 and the other is 45.
90+45=135
180-135=45°
This proves that the triangle is isosceles.
This means that two angles are equal, but also two side lengths are the same.
In this triangle, the equal sides are CB and AC.
Therefore, AC is equal to 9.
