Find the value of x and y.
i think x is 90 degrees because it looks like a right angle but i dont know how to find y.

"Drawing not to scale" tells you that you shouldn't take the picture at face value. It's possible that is not 90º.

What we do know from the picture is that

AD is congruent to itself. This means the two triangles BAD and CAD are congruent, since they form a side-angle-side pair. So it follows that

But angles BDA and CDA are supplementary, so

and it turns out your suspicion was correct after all. (Still, you should never assume things appear as they seem.)

Lastly, the interior angles of any triangle always sum to 180º in measure. This means

.
