Can somebody me with this question?

In an isosceles trapezoid the bases are parallel to each other, as represented in the image you provided.
Also remember that the legs are congruent, or the same.

So...

12 = y + 6

If 12 is the length of one leg, we will need to subtract 6 from 12 to get y. Now this is simple.

Y= 6

So to find the length of XY we will plug in our y value.

6 + 1 = 7

Thus, your length for XY is 7!

Hope this helps if you have any questions let me know!
