What are the inside angles to the nearest degree of a rhombus whose perimeter is 78 cm with an area of 270 square cm showing work?
The rhombus will consist of 4 right angle triangles each with an hypotenuse of 19.5 cm and an area of 67.5 square cm and by using Pythagoras' theorem then the quadratic equation formula their sides work out as 7.5 cm and 18 cm
Using trigonometry each triangle will have angles of 23, 67 and 90 degrees.
Therefore the rhombus will have 2 equal opposite obtuse angles of 134 degrees and 2 equal opposite acute angles of 46 degrees.
Check: 2(134)+2(46) = 360 degrees
Check: 0.5*15*36 = 270 square cm
Check: 4*19.5 = 78 cm which is the perimeter

What are the angles in a rhombus with an 80 perimeter?
The perimeter of a rhombus does not provide enough information to determine angles.
What is the perimeter of a 7.5cm rhombus?
Assuming 7.5 cm is the length of one side. Then the perimeter of a rhombus is 4 x 7.5 cm = 30 cm Like a square the four sides of a Rhombus are of equal length. It just that the angles are NOT right angles. . Its a 'lazy square'.
How do you find the measures of a rhombus with two diagonals?
That will depend on the lengths of the diagonals of the rhombus which are of different lengths and intersect each other at right angles but knowing the lengths of the diagonals of the rhombus it is then possible to work out its perimeter and area.

What is the measure of a rhombus?
The answer to this question depends on what characteristic of a rhombus you are measuring: the length of its sides, its perimeter, area, length of diagonal, its acute angles, its obtuse angles, or something else.
If a rhombus has one angle that measures 45 degrees and a perimeter of 80 ft what are the remaining angles?
Opposite angle is 45 degrees and the other 2 angles are both 135 degrees the perimeter has nothing to do with the angles.
