Answer:

x=83º

Step-by-step explanation:

The interior angle sum of a Hexagon is 720º

146+169+59+129+134+x=720

x=720-637

x=83

x=83
Step by step
You first add up all of the angles in a 6 sided polygon they equal to 720 degrees so if you add up all of the angles it equals to 637. After that you do 720 minus 637 and then you get your answer which is 83
