Suppose the rhombus is ABCD.
Consider the triangle ABC, whose area will be 40/2 = 20 sq cm.That is, 0.5*AB*BC*sin(B) = 20
sin(B) = 40/225 = 0.1777... recurring.
Therefore B = arcsin(1.777...) = 0.1787 or 2.9629 radians or equivalently, 10.24 or 169.76 degrees.

Does a rhombus have no right angles and 3 congruent sides?
A rhombus has four congruent sides. The angles don't matter, but if they're right angles, then the rhombus is a square.
Why is a square always a rhombus but a rhombus is sometimes a square?
Both have sides of equal length so that a square is also a rhombus. But a the angles of a rhombus need not be right angles so it may not be a square.
Can a square always be a rhombus?
No if it is a Square the has 4 angles and 4 sides than it could not be a Rhombus
Is a square and a rhombus the same?
No. Any square is also a rhombus, but the reverse is not true. A rhombus is a parallelogram having all four sides equal. A square is a rhombus in which all the angles are right angles.
Is rhombus different than square?
Yes, a square is a rhombus, but a rhombus is not a square. Yes, a rhombus has four sides of equal length. A square is a rhombus with four right angles.
What shape has 4 equal sides no right angles?
A rhombus has 4 equal sides. Its angles can be right angles, but don't have to be. A square is a type of rhombus.
Does a rhombus have no right angles and 3 congruent sides?
A rhombus has four congruent sides. The angles don't matter, but if they're right angles, then the rhombus is a square.
Are the angles of a rhombus all equal?
A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.
Is a rhombus also a square?
A rhombus can be a square, but not necessarily.A square is always also a rhombus.A rhombus has 4 equal sides with opposite sides parallel and opposite angles equal.A square has 4 equal sides with opposite sides parallel and all angles 90o.
Why is a square always a rhombus but a rhombus is sometimes a square?
Both have sides of equal length so that a square is also a rhombus. But a the angles of a rhombus need not be right angles so it may not be a square.
Is an rhonbus a square?
A rhombus just needs to have its sides equal, but a square has to have both its sides and angles equal. A square is a rhombus, but you can't say a rhombus is a square. So the answer is no.
Can a square always be a rhombus?
No if it is a Square the has 4 angles and 4 sides than it could not be a Rhombus
What is a parallelogram in which all sides are congruent?
A square or a rhombus. A rhombus does not have 4 congruent angles as a square does. It's always a rhombus. And, depending on the angles, it could also be a square. (This definition treats the square as a special case of the rhombus.)
A squashed square with 4 equal sides but no right angles?
A rhombus.
Is a square and a rhombus the same?
No. Any square is also a rhombus, but the reverse is not true. A rhombus is a parallelogram having all four sides equal. A square is a rhombus in which all the angles are right angles.
How do you determine a rectangle and a rhombus as a square?
A rectangle is a square if all sides are the same length. A rhombus is a square if all angles are right angles (90o).
When a rhombus is a square?
ALWAYSevery square is a rhombus, but every rhombus is not a square.A square must have right angles and a rhombus does not have to have those.A rhombus is a quadrilateral with equal length sides, and can have oblique angles or right angles. A square only has right angles. A rhombus with right angles is a square. Other rhombi are not squares.By these definitions, all squares are rhombi, but not all rhombi are squares
