Answer 3

the m is really a b

Answer 4

Got it :)

Answer 5

Ok to start with what kind of angles are <1 and <4?

Answer 6

I don't know

Answer 7

this is all that on the page

Answer 8

Theres a list of possibilities such as
alternate exterior
alternate interior
corresponding
do these terms sound familiar?

Answer 9

yes

Answer 10

Ok do you know what those mean?

Answer 11

no

Answer 12

OK but how does this help

Answer 13

Well your image shows something similiar

Answer 14

oh i see

Answer 15

They are both opposite to each other which means that they are equal

Answer 16

So if m<1=100 then m<4=?

Answer 17

ok so can we find the answer now

Answer 18

Yeah that's for you to find out :)
Remember I said OPPOSITES are EQUAL
So if m<1=100 then m<4=?

Answer 19

<4=80

Answer 20

How did you get 80?

Answer 21

i mast up I took a hundred and divided it by 2 and got 50 i do not no why i said 80

Answer 22

Hmm you are over thinking it my friend! Let's put it this way
Remember I said OPPOSITES are EQUAL
so... m<1=m<4
m<1=100
m<4=?

Answer 23

m<4=1

Answer 24

No worries.

Answer 25

It says `OPPOSITE ANGLES ARE EQUAL `
so...
if m<1=100
and m<4 is the oppiste angle of m<1
what is m<4?

Answer 26

i get that but I can't rap my head a round it

Answer 27

You don't need to. It's pretty simple maybe you are just over thinking it.

Answer 28

The image says `OPPOSITE ANGLES ARE EQUAL`
If m<1=100
and m<4 is the oppiste angle of m<1
what is m<4?
They are equal.

Answer 29

m<4=100

Answer 30

Ye good job!!! :D

Answer 31

thank you so much :)

Answer 32

No problem :)
