The length of TU in the parallelogram is 8 units.
What is a parallelogram?
A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
In other words, a parallelogram is a two-dimensional geometrical shape whose sides are parallel to each other
The diagonal of a parallelogram bisect each other.
Therefore, the diagonals of parallelogram QRST intersect at point U.
TU = 9x − 1 and RU = 5x + 3
Hence,
9x - 1 = 5x + 3
9x - 5x = 3 + 1
4x = 4
divide both side by 4
4x / 4 = 4 / 4
x = 1
Therefore,
TU = 9x - 1 = 9(1) - 1 = 8 units
