B) x=71, y=98
C) x=81, y=108
D) x=71, y=108

Answer 1

Is there an image?

Answer 2

Well because they are supplementary, x has to equal 71

Answer 3

and in all quadrilaterals, the interior angles add up to 360, so y equals?

Answer 4

100+81+71=252

Answer 5

360-252= 108

Answer 6

y=108

Answer 11

I want you to try solving this, after the few we did together

hint: start with 180(n-2)

Answer 13

okay , so would i replace n with how many sides there are on this shape ?

Answer 14

Yep, so 5

Answer 15

so , 180(5-20)= 540.
what do I do after that.. lol

Answer 16

I meant 2 not 20.

Answer 17

Sorry internet cut out

Answer 18

Ok so you know already about the first 340 degrees of the pentagon

Answer 19

so 540-340=200

Answer 20

so what's left is 7x+8 and 5x

Answer 21

add them to get 12x+8

Answer 22

Are you following?

Answer 23

kinda lol it's all really confusing to meee.

Answer 24

Any questions?

Answer 25

i don't understand the part right before you said are you following ? i don't understand how you added or what you did to get 12x+8

Answer 26

You know about the first 340 degrees

Answer 27

you are missing 200

Answer 28

the measurements you don't know are 7x+8 and 5x

Answer 29

but you know that 200 is 7x+8 and 5x added

Answer 30

so when you add you get.... 12x+8

Answer 31

oh , okay i understand how you got it . lol

Answer 32

so now subtract 8 from both sides, you get 12x=192
And Finnish off by dividing both sides by 12 and getting?

Answer 33

16

Answer 34

You got it!

Answer 35

I'm getting off, I hope I helped

Answer 36
