Answer:75

Step-by-step explanation:

180-64 gives you the angle not labelled which is 116 then to work out size of angle formula is 180(n-2) n being sides so 180(6-2) = 720 so 720 minus all the angles = 75 I think lol

Answer:

x = 75

Step-by-step explanation:

180-64 = 116

Since this is a hexagon (6 vertices), the angles all add up to 720

116 + 121 + 155 + x + 90 + 163 = 720

x + 645 = 720

x = 75
