In a parallelogram, the diagonals bisect each other but are not necessarily equal in length. Therefore, without specific lengths of the sides, we cannot determine the lengths of the diagonals RT and SU.
However, if you know the lengths of specific sides or angles, you can use the properties of triangles or the law of cosines to find the lengths of the diagonals. In a typical parallelogram, the lengths of the diagonals can be found using the following formula if you know the lengths of the sides \( a \) and \( b \) and the angle \( \theta \) between them:
\[ \text{Length of diagonal RT} = \sqrt{a^2 + b^2 - 2ab \cos(\theta)} \]
\[ \text{Length of diagonal SU} = \sqrt{a^2 + b^2 + 2ab \cos(\theta)} \]
If you provide more specific information, I can help you calculate the lengths of the diagonals.
