Question

I don't understand this please help me??

Answer 1

I know A is given but would I write given? Or would I write?..... Please help

Answer 2

what don't you understand? That way I can help you

Answer 3

Well a is given right @katti ?

Answer 4

Right, A= 40. B is also given.

Answer 5

I would write 40 or given one of my friends told me to just write given?

Answer 6

both would work :)

Answer 7

For the rest I feel clueless @katti

Answer 8

Well, supplementary angles has add up to 180. So 40+140 would have to equal 180.

Answer 9

And they also are the same-side interior angles. So If they do add up to 180, because they are same-side interior, the lines A and B are parallel.

Answer 10

Yes ok @katti I think I'm understanding so far.

Answer 11

kk, is there anything that you still are confused about?

Answer 12

Well for c, and C would be supplementary angles because =180? I hope you don't mind helping me through all the way. @katti

Answer 13

Not at all!
Supplementary angles are 2 angles that were added up and they equaled 180 degrees.

Answer 14

So c therefore would be supplementary?

Answer 15

right

Answer 16

same for d?

Answer 17

you got it!

Answer 18

Are we doing it right it says... State the missing reasons in this flow proof. So far I got a.40, or given. b 140 or given, c. Supplementary angles D. Supplementary angles?@katti

Answer 19

@sleepyjess @iGreen can you guys help check?

Answer 20

Oh! sorry, uhh...for D, it would be that the angles are same side interior. They are both inside the 2 line and on the left side of the intercepting line

Answer 21

What about e?

Answer 22

can u helpme

Answer 23

because angle 5 and 2 are supplementary and same-side interior, the lines A and B are parallel.

Answer 24

So what would end up being @katti

Answer 25

E??* @katti
