    So you would do
    29*2= 58

    180-58=122

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

    j=B=E

    j=108

    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
    This adds to 252

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

    j=108

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