Answer:
I don't have a picture but since it is a rhombus, I'll give it my best shot.
IF those two angles are across from each other, they are equal, then:
2x+4 = 5x-5
add 5 to each side of the equation:
2x+9 = 5x
subtract 2x from each side:
3x = 9
divide both sides by 3:
x = 3
IF those two angles are adjacent, their sum is 180°, then:
2x+4 + 5x-5 = 180°
combine like terms:
7x - 1 = 180
add 1 to each side of the equation:
7x = 181
divide both sides by 7:
x = 25.86
