Answer:
x = 19.25
Step-by-step explanation:
The diagonal of a rhombus bisects opposite angles and opposite angles are congruent.
So, 2x - 1 is the measure of the third angle of the triangle
Therefore, 2x - 1 + 2x - 1 + 4x + 28 = 180 since the sum of the measures of the angles of a triangle is 180
8x + 26 = 180
8x = 154
x = 19.25
