Answer:
11.x=100
12.x=118
Step-by-step explanation:
using the interior angles theorem the space below x is 80 degrees
the space below 80 is x
Every paralellogram equals 360 degrees
add all angles and subtract from 360 to find x
80+80+x+x=160+x2
x2=200
x=100
Use the same thing for 12
62+62+X+X=360
124+2X=360
2X=236
x=118
