Question

help with a geometry question?

Answer 1

So there's this. 2 parallel lines and angle measure 90.

Answer 2

By alternate interior angels

Answer 3

heres what ive done so far: im not so sure if its right though.
5x=90/5
x=18

9y=90
y=10

x=18
y=10

Answer 4

Oh wow...yeah you're right

Answer 5

really?

Answer 6

9y = 90
5x = 90

yeah

Answer 7

i have a few more if you can help..ive done them i just need a help with a couple and to be checked if thats alright

Answer 8

@mhchen

Answer 9

Okay.

You know that angle (y+8) is equivalent to angle (3x+5) right?

Wait did you solve these problems already or do you need help to solve them.

Answer 10

this one i did
3x+5+6x-14=180
9x+9=180
9x=171
x=19
i didnt know how to do the rest.

Answer 11

or does y just equal 8?

Answer 12

or would y=172?

Answer 13

Hold on. On your second step:
9x + 9 = 180, it should be 9x - 9 = 180

Answer 14

ohh

Answer 15

wait what wouldnt it be plus?

Answer 16

3x + 5 + 6x - 14 = 180
9x + 5 - 14 = 180
9x - 9 = 180

Answer 17

3x+5+6x-14=180
9x+5-14=180
9x-9=180
9x=189
x=9.9
oh

Answer 18

wait
9x = 189
x should be 21 then

Answer 19

ohh i divided on my calc 19 for some reason lol

Answer 20

Alright. And then

If these 2 lines are parallel (marked with arrows)
then angle A = angle B

Answer 21

what so would y=21????????

Answer 22

I got 60.

x = 21.
Angle A is (3x+5)
which is (3(21) + 5) = 68

Angle B is 68, and it's also y + 8
68 = y + 8

Answer 23

wait what???? im trying to find the missing values of x and y

Answer 24

Yeah, you found x. Which was 21.
And then you use x to find the angle measure of this:

Answer 25

A and B are the same.

And you know B is y+8.

So you find Y by solving 68 = y + 8

Answer 26

ohh whered you get 68 from?

Answer 27

oh got it

Answer 28

next one?

Answer 29

8x+40+6x=180
14x+40=180
14x=140
x=10

3y-10+7y=180
10y-10=180
16y=190
y=19

Answer 30

Yeah that looks right. I assume you had a typo when you wrote "16y=190" instead of "10y = 190"

Answer 31

oops, yeah sorry lol

Answer 32

3x-15=2x+7
x=22

Answer 33

ye

Answer 34

do i need to find y?

Answer 35

There is no y in that picture.

Answer 36

ok good

Answer 37

3y+72=180
3y=108
y=36

x+72=180
x=108

Answer 38

Yeah that seems right so far.

Answer 39

so far??

Answer 40

You still need to solve for z.

Answer 41

oh on my paper it just says find x and y

Answer 42

Oh well then, ignore Z I guess lol

Answer 43

haha one more?

Answer 44

kk

Answer 45

My profile picture is TERRIFYING

Answer 46

y+12+y-18=180
2y+30=180
2y=150
y=75

x=75

Answer 47

haha

Answer 48

i know it went from a cute pfp to a scary one

Answer 49

y + 12 + y - 18 = 180
2y - 6 = 180 There's your first mistake

Answer 50

oh x=93?

Answer 51

y*

Answer 52

wait
y+12+y-18=180
2y-6=18-
2y=186
y=93

Answer 53

Oh yeah I'm dumb

Answer 54

Brainfarts happen. You're right.

Answer 55

haha and is x=12?

Answer 56

How did you get X though, it should be 90. Wait just to clarify

Answer 57

is this X?

Answer 58

yeah thats what i did

Answer 59

Then by corresponding angles, it should be 90.

Answer 60

oh

Answer 61

wouldnt it be 93?

Answer 62

Right-angles are always 90.

Answer 63

oh, sorry, my brain isnt working

Answer 64

thanks so much for all your help!
