  1. In a rhombus, opposite angles are equal, and the diagonals bisect the angles.
    So if angle DAC = x+10
    then angle DAB = 2x + 20

    then 5x-10 = 2x+20
    3x = 30
    x = 10

    Can some one please check these for me.Thanks Angle DEF is similar to Angle HJK and the scale factor of angle DEF to anle HJK IS 5/2. If EF =15 FIND JK Here is what I came up with Am I correct 5/2 = EF/JK 5/2 =15/JK 5(JK)=30
