Question

Can someone check my answer? Thank you!

Answer 1

I think it is C.

Answer 2

Or would it be 40?

Answer 3

Um..

Answer 4

No, I don't get C. The angles in a quadrilateral sum to 360. And angles in a linear pair sum to be 180.

Answer 5

Let me try to do it again.

Answer 6

HI!!

Answer 7

i don't think it is C

Answer 8

Ok. :)

Answer 9

Ok..I think I see it's not C.

Answer 10

You need 270 correct?

Answer 11

I belive so

Answer 12

\[40+80+110=230\]

Answer 13

You're missing 40 degrees.

Answer 14

So it would be 40

Answer 15

x=40?

Answer 16

That's what I'd put...

Answer 17

Can you check one more?

Answer 18

I don't get 40.....

Answer 19

I picked B

Answer 20

@JoannaBlackwelder what do you get?

Answer 21

Oh, ok. Yes,I get B. :)

Answer 22

Joanna, for the first question you got 40?

Answer 23

Or are you saying the second question is right?

Answer 24

For the first question, I got 50.

Answer 25

And no, the second question isn't right. :/

Answer 26

So then I'm not sure what it is...40 or 50....

Answer 28

Oh darn...I thought I had the second question. :(

Answer 29

What do you get for the sum of the 3 angles you have?

Answer 30

3 angles in the quadrilateral.

Answer 31

230

Answer 32

You were close on the second one though. :)

Answer 33

Okay...can you help me on the second, then?

Answer 34

@JoannaBlackwelder

Answer 35

Good, so what do you need to add to that to get the sum of all the angles in the quadrilateral to be 360?

Answer 36

Wait, do you do understand the first one? I gave you a link to the answer for the second one.

Answer 37

This link has the answer to the second one:

Answer 38

the second questions is D?

Answer 39

Right! :D

Answer 40

yay!!

Answer 41

For the first question now,

Answer 42

Ok :D

Answer 43

What do you get for the 4th angle in the quadrilateral?

Answer 44

What do I need to do to get the correct answere. You told me 50 and others told me 40

Answer 45

40

Answer 46

It can't be 40, since we need 230+(4th angle) = 360

Answer 47

That means that the 4th angle in the quadrilateral must be 130.

Answer 48

Then x is a linear pair with the 4th angle in the quadrilateral. So, the sum of those two angles must be 180.

Answer 49

130+x=180

Answer 50

50

Answer 51

:D

Answer 52

Okay...Can I ask you to check 1 last question?

Answer 53

I['m sorry. I am not good at math

Answer 54

It's no problem. :)

Answer 55

Yes, you are welcome to ask. :)

Answer 56

Yes, great job!

Answer 57

Thank you!!

Answer 58

Since the measures of exterior angles always sums to 360, each must get smaller when you have more sides. :)

Answer 59

You are very welcome!

Answer 60

Thats what I was thnking.

Answer 61

Awesome!
