In a rhombus, all angles add up to 360 degrees. Angle D and angle B are equal, so you can add 65 and 65 to get 130. To find angle C, you need to do 360-130 to get 230, and divide that by 2 to get 115. To get angle y, do 360-115 to get 245, as there are 360 degrees when you add angle C and y. Therefore, angle y is 245 degrees.
