So you would do
29*2= 58

180-58=122

B= 360-(130+122)
B= 108

j=B=E

j=108

Can you explain it all because i don't understand why i would do that and answer the top question

what reason would b=e alternate angles?

So I did 29*2 cos the angle next to k is also 29...

I took the answer (58) away from 180 (122) to find the angle inbetween B and 130
180-58=122

I saw that angles vertically opposite are equal
So j=E

And then I saw that E=B because in a rhombus, opposite angles are equal

So j=E=B
They are all equal

Then to find B, I did 130+122

To find B I had to do 360-252= 108
B=108
so j=E=108

j=108

Hello..
I told you, angles opposite in a rhombus are equal...
