Answer: X= 5
because in a rhombus the diagonals bisect the angle (cut the angle in half) so you just need to set the to equations equal to each other
2x+4=5x-11
then you solve
you subtract the 2x from the 5x
4=3x-11
then you add the 11 to the 4 and you end up with
15=3x
you want X by its self so you divide both sides by 3 and you end up with
X=5
