Question

Ok, I still don't get this. /:

Answer 1

6

Answer 2

A full circle is 360degrees

Answer 3

I helped some other person earlier this week with this: it's not the same thing, but perhaps you'll get an idea.

Answer 4

\[AB+BC+CD +DA=360\]

Answer 5

look up alternate interior angles for A

Answer 6

Well, I get that they equal 360, but how to get just arc BC is what stumps me

Answer 7

you already have mDA ...
... you need mAB & mCD

Answer 8

Yeah, how do you find that?

Answer 9

you can get AB from \(m\angle C\)

Answer 10

So 68 and 44?

Answer 11

yes

Answer 12

So the answer is 120?

Answer 13

yes.

Answer 14

I used a different approach, but you do get the same answer in the end.

Answer 15

Oh gosh, I wish I could give a medal to both of you guys.
