Answer 4

quick

Answer 5

ok one sec

Answer 6

one sec is over

Answer 7

its 2 minutes

Answer 8

if you can't help me and you got stuff to do that's fine ..

Answer 9

no I was just joking sorry if u felt bad

Answer 10

oooh okay I didn't know, but here's the caption

Answer 11

so its said 8 = 150

Answer 12

no 115 but i don't know the measure for angle 1 and 4

Answer 13

/_8 wht is this is it only 8 or something else

Answer 14

@iGreen

Answer 15

@adorablefourfootnine

Answer 16

umm I'm not sure ? all i know is that its asking what is the sum of angles 1 and 4

Answer 17

before that u gonna know this /_8

Answer 18

bc i dont understand wht is this

Answer 19

I don't understand your question :/

Answer 20

wht is this /_8

Answer 21

oh! it's a symbol for angle 8

Answer 22

@amorfide do hve any idea okay

Answer 23

@AnswerMyQuestions

Answer 24

okay i get it

Answer 25

its angle 8 measures 115

Answer 26

correct

Answer 27

I think angle 5 should also measure 155 because oposite angle

Answer 28

angle 8 = angle 5

Answer 29

not sure

Answer 30

quick i cant wait i suck in keeping patience

Answer 31

i don't know either... do you know someone who can help me?

Answer 32

@AnswerMyQuestions

Answer 33

isn't angle 1 same as angle 8

Answer 34

idk how to work out angle 4

Answer 35

i think angle 8 is same as angle 5

Answer 36

I don't understand this...

Answer 37

yea but it's opposite angles though

Answer 38

@AnswerMyQuestions read everything

Answer 39

that is also true

Answer 40

I remember doing traversals, but never exactly understood them...

Answer 41

opposite angles r equal

Answer 42

*transversals

Answer 43

if angle 8 = angle 5 = angle 4

Answer 44

angle 4 = 115

Answer 45

I believe angle 4 is angle 8 and angle 1 is angle 4 so 115+115
since opposite angles

Answer 46

might be wrong though

Answer 47

@amorfide how is it same they are way diferent

Answer 48

@ganeshie8

Answer 49

how is that possible though? i don't understand

Answer 50

I think angle 8 = andle 5 = angle 4

Answer 51

actually let's do this

Answer 52

so if you draw a line from angle 8 to form a straight line you get 180-115 is the angle on the outside so you get 65
which i think makes angle 6 65
since 6 and 4 are in a parallelogram you get 65+65=130 so angle 4 is 360-130 then divide by 2 to get 115
so angle 4 is 115
angle 1 is 115
so 115+115=230

Answer 53

therefore the sum is 230

Answer 54

or you can say that since the bottom left quadrant is equal to top right quadrant you can put angle 8 and angle 1 opposite to each other opposite angle states angle 1 is angle 8 so angle 1= 115

next you can say that the sahpe angle 1 is in matches the shape of the quadrant and has the same angle for the angle the dotted line forms
therefore the opposite angle would be angle 4 since we know angle 1 is 115 then angle 4 is also 115
therefore the sum of angle 1 and angle 4 are 115+115 = 230

Answer 55

since you have

Answer 56

then these angles are equal

Answer 57

so 1=4
and 1=8
therefore they are the same angle

Answer 58

yup, @adorablefourfootnine can you please medal me

Answer 59

Thank you so much @amorfide for the help , and sure @Adi3 is it possible to medal more than one person?

Answer 60

You are welcome, if it doesn't make sense I could probably draw it step by step

Answer 61

8 = 5 (vertically opposite angles)
5 = 1 (corresponding angles)
so, angle 1 = 115
also, 8 = 4 = 115(corresponding angles)
1+ 4 = 115+115 = 230

Answer 62

yeah akita explained it better

Answer 63

yes

Answer 64

no

Answer 65

sorry u already medaled him

Answer 66

i don't know how to do that though @Adi3

Answer 67

u cant

Answer 68

yeah i wanted to do both , you said its possible , so how do i do that

Answer 69

i thought u dint medal anyone

Answer 70

but all the credit goes to @amorfide

Answer 71

dang :/
