Answer 1

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

Hope this helps
