Question

If quadrilateral ABCD is a parallelogram, what are the correct values for x and y?

Answer 1

help please !!!

Answer 2

adjacent angles of a parallelogram add up to 180 degrees
opposite angles of parallelogram are equal to each other

opposite sides of a parallelogram are equal to each other

Answer 3

these are my possible answers

Answer 4

x = 30, y = 3


x = 30, y = 2


x = 70, y = 2


x = 70, y = 3

Answer 5

from the rules I stated you can get
x+40 = 100 - x

and 5 - y = y + 1

Answer 6

I got 60 for the first one but its not one of my answer options :(

Answer 7

close :)
but don't forget the other x
x+40 = 100 - x add x to both sides
+x +x
so 2x + 40 = 100 then minus 40 from both sides
-40 -40
2x = 60 then divide both sides by 2

Answer 8

oh okay got it so x=30

Answer 9

yes :)
then try
5 - y = y + 1

Answer 10

im doing something wrong because I got 4

Answer 11

is it minus 5 ?

Answer 12

it was the same mistake as before :)
don't forget that you have to move the other "y" as well
so 2y = 4 divide both sides by 2

Answer 13

okay so my answer is B THANK YOU (:

Answer 14

You're Welcome ^_^

Answer 15

Can you help me with this one lol

Answer 16

Which of these sentences is always true for a parallelogram?

All sides are congruent.


All angles are congruent.


The diagonals are congruent.


Opposite angles are congruent.

Answer 17

scroll up to my first comment, what did I say? :P

or you can do process of ellimination
All sides are congruent. -> square, not necessarily all parallelograms
All angles are congruent. -> rectangle, not necessarily all parallelograms
The diagonals are congruent. -> rectangles, not necessarily all parallelograms

Answer 18

I think its D

Answer 19

correct :)

Answer 20

Thank you, Im taking a geometry class online & you were really helpful

Answer 21

I'm glad I could help :)

Answer 22

What is the reason for the third step in this proof?
