https://prnt.sc/le4q5j (#7-13)

Answer 2

#7
<4 and <5 are alternate interior, they are the same measure

Answer 3

#8,9 will be resolved once 7 is fixed

Just make sure to re-do them

Answer 4

for #7 arent i trying to find x?? how do i do that?

Answer 5

You set them equal to 180

Its supposed to be
\(4x+15=6x-25\)

Answer 6

wait do i do
4x+15=6x-25
?

Answer 7

Right

Answer 8

yea

Answer 9

4x+15=6x-25
2x+15=-25
2x=-40
x=-20
is this right?

Answer 10

Not quite
\(4x+15=6x-25\\
\color{red}{2x}+15=-25\\
2x=-40\\
x=-20\)

You got the wrong sign here
4-6 is -2 not 2

Answer 11

oh
4x+15=6x−25
-2x+15=−25
-2x=−40
x=20

Answer 12

Yes

Answer 13

That is your answer to #7

Answer 14

sorry, it takes me a little while to solve

Answer 15

For #8
Substitute 20 in for x
\(4x+15\)

Its okay, take your time

Answer 16

4x+15
4(20)+15
80+15
95

<4=95º

Answer 17

Yeah, assuming that the measures are right

You do have a point in saying that <1 is congruent to <4, but the teacher said it was wrong no?

Answer 18

he just told me that #7-13 were incorrect

Answer 19

Okay then it was wrong, 95º is your answer

Answer 20

For #9

Substitute 20 in for x
\(6x-25\)

Answer 21

ok.
6x-25
6(20)-25
120-25
95
<5=95º

Answer 22

Yeh

Answer 23

this may be a dumb question, but why are we substituting x with 20?

Answer 24

oh from #7

Answer 25

Yes

Answer 26

how would i do #10?

Answer 27

It looks right, I am not sure what went wrong hmm

They are same side exterior which are supplementary

Answer 28

yeah i had a friend tell me too that they thought that i was right. im not sure.

Answer 29

Maybe ask your tutor to re-check?

Answer 30

ok. should we move onto #11, 12, and 13 with <7 being 50?

Answer 31

For #11
They also look right

They are supplementary.. hmm

#12 and 13 are also right because of this

lolwut

Answer 32

What a good tutor, hunting out your mistakes rather than your successes.

Answer 33

Oh 13 re-check math

Answer 34

@dude
sorry, i fell asleep on you there.

would <3=94.5?

Answer 35

oh wait sorry i did 12

Answer 36

Uh
\(3(21.8)+20\)

Answer 37

Yeah

Answer 38

<3=85.4

Answer 39

Yeah
