Okay so you need to know that 80+20+x=180

6. phi

if you ignore the slanted line on the left you have |dw:1438868062211:dw|

7. anonymous

Wait never mind about that equation.

8. anonymous

i belive its 100

9. phi

if we add in the slanted line: |dw:1438868175575:dw|

10. anonymous

|dw:1438868196383:dw|

11. phi

notice x + 20 has to add up to the 80

12. anonymous

Oh lol sorry I didn't mean to copy you there @phi

13. phi

it's ok

14. anonymous

The actual equation would be x+20=80. Solve for x now.

15. anonymous

so they add uo to each other

16. anonymous

its d 100

17. anonymous

No. You have to subtract 20 from both sides. Don't add 20 on both sides.

18. anonymous

oh ok

19. anonymous

so its 60?

20. anonymous

Yes.

21. anonymous

so do i do same thing with this

22. anonymous

With what?

23. anonymous
24. anonymous

Here is kind of different. You know that angles 5 and 6 equal 180 right?

25. anonymous

*180 degrees

26. anonymous

yes

27. anonymous

So if you know what angle 6 is then you just need to put it to an equation.\[Angle5+Angle6=180\]\[Angle5+97=180\]Think of Angle 5 as x.\[x+97=180\]

28. anonymous

Now solve for x.

29. anonymous

so you mean they add into 180

30. anonymous

Yep!

31. anonymous

i belive x = 83

32. anonymous

right?

33. anonymous

Yes that is correct! :)

34. anonymous

i have one more question but i think i already answerd it https://gyazo.com/fabff3ae5fb53695c92ed256ffdc8557

35. anonymous

i belive its congruent

36. anonymous

Congruent means that the angles are the same. But in this case the angles are different because of their size. They would actually be supplementary angles because both angles equal 180 or add up to 180.

37. anonymous

ok

38. anonymous

These angles aren't adjacent though since they don't share a vertex. So which answer choice do you think it is?

39. anonymous

a

40. anonymous

Yes that is right!

41. anonymous

ok thx

42. anonymous

You're welcome! :)
