Answer: 148
A triangle = 180
So all three sides have to add up to 180.
If one side is 12 And the other is 20 you add that makes 32.
12 + 20 = 32
Now we need to find the length of the other side. 32 is two of the sides and 180 is the whole. So something + 32 = 180
32 + x = 180
To find x you subtract 32 from 180
180 - 32 = 148
