    A rhombus has the following properties: Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular; that is, a rhombus is an orthodiagonal quadrilateral. Its diagonals bisect opposite angles.

    AD is parallel to CD therefore <DAC = <BCA by alternate interior angles theorem

    Then use the fact that the diagonals meet at 90 degrees. So we have a triangle that has angles x, 3x-26, 90. Add them up to equal 180, the sum of the angles of any triangle.

    Properties of the diagonals of a rhombus: The intersection of the diagonals of a rhombus form 90 degree (right) angles. This means that they are perpendicular. The diagonals of a rhombus bisect each other. To prove that the diagonals of a parallelogram bisect each other, we will use congruent triangles: (alternate interior angles are equal in measure) (alternate interior angles are equal in measure). (since these are angles that a transversal makes with parallel lines AB and DC). remember that the diagonals of any parallelogram bisect each other and the diagonals of a rectangle are congruent. not sure about the square but the other 3 correct
