Answer:

Step-by-step explanation:
This is an irregular pentagon, so the total degrees is 540
Add the know degrees together.
131+108+107+110 = 456
Then subtract 456 from 540
540 - 456 = 84
x= 84
Another way you could have done this is by making the following equation.
131 + 108 + 107 + 110 + x = 540 solve
456 + x = 540
-456 -456
x = 84
