Of course I know, but you have to learn too :)
Now, what angle forms a straight line? ^_^

I'll try my best to get you up to speed, but I might just fall asleep any moment now, so if I don't respond within a minute, then, I'm probably down :)

Answer 19

@iceicebaby You still there?

Answer 22

What angle forms a straight line?

Answer 23

give me a sec

Answer 24

don't take too much time :)
seriously... I'm so tired D:

Answer 25

would it be 180?

Answer 26

YES. Exactly. 180.
Now, since they form a straight line, they have to add up to 180.

60 + 80 + x = 180

Now solve for x. :)

Answer 27

ok

Answer 28

well then x would be 180 correct ? @terenzreignz

Answer 29

replace x with 180 and check.

Answer 30

ok

Answer 31

And... is it correct?

Answer 32

I'm really tired, now, @iceicebaby
ten minutes, I'm signing off... so you'd do well to make the most of it :)

Answer 33

yeah i think so

Answer 34

60 + 80 + x = 180
replace x with 180

60 + 80 + 180 = 180

is it correct?

Answer 35

x has to equal 40 then

Answer 36

cause if you replace 180 with x then it would have to be 40 if they all equal 180 together

Answer 37

x has to equal 40, yes.
And that's the answer.

Good job... finally ^_^
