ABCD is a rhombus. Find AB. Give answer as a fraction in simplest form.

The length of AB = 97/3 units

Step-by-step explanation:

We know that a rhombus is a quadrilateral whose four sides all have the same length.

Thus, the equation becomes

7x+2 = 4x+15

7x-4x = 15-2

3x = 13

x = 13/3

So, the length of CD = 7x+2 = 7(13/3)+2

                                               = 91/3 + 2

                                               =  97/3

And, the length of BC = 4x+15 = 4(13/3) + 15

                                                  = 97/3

Thus, the length of AB = 97/3 units
