A rhombus is a four sided quadrilateral whose total sum of interior angles amount to 360 degrees. Opposite angles are equal in a rhombus. Therefore: 35 degrees+35 degrees = 70 degrees. 360 degrees - 70 degrees = 290 degrees which then is split in two to give you the other two angles: 290/2 = 145 degrees. So the answer to your question is A 35 degrees 145 degrees 145 degrees.
