Answer:
D 138
Step-by-step explanation:
To find the sum of the interior angles of a polygon, use the formula
sum = (n-2)*180 where n is the number of sides
This is a six sided figure, so n = 6
sum = (6-2) * 180 = 4*180 = 720
Add up all the interior angles
720 = 85+152+x+85+135+125
Combine like terms
720 =582+x
Subtract 582 from each side
720-582 = 582+x-582
138 = x
