Two adjacent angles of a parallelogram are $(2x+25)°$ and $(3x-5)°$. The value of $x$ is 

The diagonals do not necessarily intersect at right angles in a 

The length and breadth of a rectangle are in the ratio $4:3$. If the diagonal measures $25 \mathrm{cm}$, then the perimeter of the rectangle is

The bisectors of any two adjacent angles of a parallelogram intersect at

If an angle of a parallelogram is two-thirds of its adjacent angle, the smallest angle of the parallelogram is 

The diagonals do not necessarily bisect the interior angle at the vertices in a 

In a square $\mathrm{ABCD}$, $\mathrm{AB}=(2x+3) \mathrm{cm}$ and $\mathrm{BC}=(3x-5) \mathrm{cm}$. Then, the value of $x$ is

If one angle of a parallelogram is $24°$ less than twice the smallest angle, then the largest angle of the parallelogram is
