## Fang02 2 years ago I'm a bit confused on how to do this problem. What is angle 1 in this parallelogram? Diagram will be in the comments. Options: o 20 degrees o 60 degrees o 80 degrees o 100 degrees I tried working out the problem, but couldn't find the right answer. I believe that the slope = 10. Any help?

where is the diagram

I think I made it a little more slanted then it really is.

5. Piggiepigpigs

160

6. Piggiepigpigs

sorry I meant 80

7. Piggiepigpigs

3m+5m+20=180 8m+20=180 8m=160 m=80

8. Piggiepigpigs

M=20 Plug that back in and M<1 =80

9. Piggiepigpigs

Sorry for the confusion

10. Fang02

Sorry if I suddenly disappear, my internet connection is messing up. I'm still here. I'm going to read over your comments right now.

11. Fang02

Why does m equal 20?

12. Piggiepigpigs

yes

13. Fang02

Why does it equal 20?

14. Piggiepigpigs

Because when you set 3m+20+50=180 and you simplify you get m=20

15. Fang02

Where did the 50 come from?

16. Piggiepigpigs

That was supposed to be 5m

17. Fang02

Here's what I did: 5m + 3m + 20 = 180 8m + 20 = 180 Subtract 20 on both sides 8m = 160 Divide 8 on both sides m = 80 I understand that...

18. Fang02

Oh wait I get it now. Sorry. ^^;

19. Piggiepigpigs

That is exactly what I have shown you

20. Fang02

I know, I did it to follow along, but I thought wrong on the last part. Just a moment please.

21. Fang02

Thank you very much for your help.

Have a great day/night!

24. Piggiepigpigs

You too and if you need any more help in geometry let me know

25. Fang02

Okay, will do. :)
