i think the answer is A.

Answer: 12

The value of y= 12.

Step-by-step explanation:

We know that the diagonal of rhombus are perpendicular bisector of each other.

i.e. the angle made at the intersection of diagonal is 90 degrees.

Thus , for the given figure m∠1 = 90°

Since it is given that  m∠1 = 8y-6

Thus , 8y-6= 90

⇒8y=96   [Adding 6 both sides]

⇒ y = 12  [Dividing both sides by 8]

Hence, the value of y= 12.
