## CBARREDO1 one year ago If BD bisects <CBE, the m<CBD=5x, and the m<CBE=8x+16, find the m<ABC

ok we know ABE=180

3. CBARREDO1

Yes

4. anonymous

then ABC= 180-(8x+16)

5. CBARREDO1

Ok, where did you just pull that out from

6. anonymous

ok

7. anonymous

i ll explain

8. CBARREDO1

No, i got it

9. CBARREDO1

It's just that I've been at this for hours and you made it so simple

srry angle ABC+ 5x+(3x+16) =180

12. anonymous

i forgot the brackets

13. CBARREDO1

14. anonymous

yes u can say that too

15. anonymous

but to show you how 180 is equal that term i showed all the individual terms

16. CBARREDO1

ok

17. anonymous

do u need help solving or u good?

18. CBARREDO1

ABC+8x+16=180 ABC+8x=164 ABC+x=

19. CBARREDO1

After that I'm stuck

20. anonymous

well they are asking for equation $ABC= -x+20.5$

21. anonymous

because $\frac{ 164 }{ 8 } =20.5$

22. CBARREDO1

Ok

23. CBARREDO1

But it is telling me to find m<ABC

24. CBARREDO1

25. anonymous

you just did

26. CBARREDO1

I need to get the angle, not just the equation

27. anonymous

m<ABC=-x+20.5

28. CBARREDO1

Yea, but how do I find the angle now

29. anonymous

you cant get the angle because we dont know the x variable

30. anonymous

or we can use substitution

31. CBARREDO1

Then I guess that is the answer, thank you very much. Math can be a pain sometimes.

32. anonymous

yea it can but i dont think u would require substitution in this question
