### How to find c and y so that each quadrilateral is a parallelogram

The opposite internal angles of a parallelogram are equal, and adjacent angles are supplementary, but which of the given angles are opposite and which are adjacent? We know that all angles must be positive, so 7x-11>0 and 5y-9>0 so x>11/7 or 1.57 and y>1.8. We also know that al

### In a rhombus ABCD, AB=18 and AC=28. Find the area of the rhombus to the nearest tenth.

The sides of a rhombus are all equal and the diagonals cross at right angles and bisect each other. If the diagonals are drawn the rhombus can be seen to consist of 4 right-angled triangles, with the sides of the rhombus being the hypotenuses. The side of the rhombus is 18 and the len

### finding perimeter and area

Perimeter is straightforward: P = 18 + 6 + 11 + 9 = 44m To calculate the area of an irregular quadrilateral you need the side lengths and the diagonal lengths. Since the diagonal lengths are not provided I'll give the formula. For: a, b, c and d are lengths of sides s is the semiperimeter, s =

### adjacent sides of parallelogram is in ratio 9:11.what are measure kf angles of parallelogram

The parallelogram could be a rectangle with side ratios 9:11, in which case the angles of the parallelogram are all 90 degrees. So that means there's not enough information in the question to find a unique solution. Let's say the actual lengths of the sides are a and b, and the lengths of the dia

### How do you find the length of the sides of a rectangle with only the diagnal length and the area?

If the sides are a and b then the area is ab and the length of the diagonal is sqrt(a^2+b^2). So if area=A, then b=A/a and if diagonal length is D then D^2=a^2+b^2=a^2+A^2/a^2. Therefore a^2D^2=a^4+A^2. So a^4-a^2D^2+A^2=0 and a^2=(1/2)(D^2+sqrt(D^4-4A^2)). The two roots of this correspond to a

### find the length of diagonal AC.

If the square has side length a, then the area of triangle FBE is 1/2*a/2*a/3=49 sq cm (half base FB*height BE). So a^2/12=49 (FB=a/2 and BE=a/3). So a^2=12*49 and a=14sqrt(3). (sqrt(12)=sqrt(4*3)=2sqrt(3).) Diagonal AC^2=2a^2 (Pythagoras), so AC=a*sqrt(2)=14sqrt(6)=34.29cm approx.

### Pythagorean Theorem

when you measure, there will be always errors for example, you may get a length of 21 inches and width of 17 inches, or whatever, when doing the calculation, it's likely that it's a irrational (square root) so there will be errors as well.
