Answer:

32

Step-by-step explanation:

The ray created by line BC has two 180° sides. Side AC intersects this ray and forms two angles. We can find this second angle by subtracting 148 from 180 to get 32.
A straight line also measures 180 degrees.

If a straight line is 180 degrees, than 148 degrees plus angle ACB must equal 180 degrees because together they make a straight line.

180 = 148 + ACB
ACB = 32 degrees
