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?

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

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

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

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.

Why does m equal 20?

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

Where did the 50 come from?

That was supposed to be 5m

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...

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