Answer:
x = 84°
Step-by-step explanation:
The sum of the interior angles of a pentagon is equal to 540°.
x + 107 + 108 + 110 + 131 = 540
x + 456 = 540
x + 456 - 456 = 540 - 456
x = 84
If you add up all of the internal angles in ANY pentagon it will be 540, so
x = 540 - (131+108+107+110)
30 m
You simply add the lengths of all the sides. 3 m is not needed for this.
