Answer: 70
Step-by-step explanation:
Because opposite sides of a parallelogram are equal, AB=CD. So,
2x-10=x+30
x=40
Therefore, AB=2(40)-10=70
Answer: I would have to say its zero
Sorry if I got it wrong
11(x-y)
you can distribute here
11x(x) and 11x(y)
11x and 11y
but don't forget the "-" sign
11x-11y is the equivalent to 11(x-y)
Both of the missing angles are 45*.
Hope I helped. :)
