If you mean quadrilateral ABCD then by using Pythagoras' theorem diagonal AC is 5 cm and using the cosine rule angle ADC works out as 41.04 degrees.
It is 40.7 degrees.

There are a few things to consider when answering this question. First, it is important to note that a rhombus is a quadrilateral with all sides being equal in length. This means that the angles of a rhombus will also be equal. Therefore, angle DCECBAE46D will be equal to the other angles in the rhombus, which are all 90 degrees. It is also important to note that a rhombus is a special type of parallelogram. This means that the opposite sides of a rhombus are parallel to each other. Therefore, the angle between the two parallel sides will also be 90 degrees. So, to answer the question, angle DCECBAE46D is equal to 90 degrees.
Perpendicular would be at a right angle. If your sides are abcd, then ab, bc, cd, and da are perpendicular pairs.

90 degrees because it's a right angle, they're always 90 degrees
for a+ NEVERIn a parallelogram opposite angles are equal. Thus angle c = angle a = 40o.The sum of all the angles in a quadrilateral is 360o, so:angle a + angle b + angle c + angle d = 360o=> 40o + angle b + 40o + angle d = 360o=> angle b + angle d = 280o.
280

No. But they add up to 180 degrees.
