Answer:
Step-by-step explanation:
The diagonals of a parallelogram cross at their midpoints. This means the segments of each diagonal are equal in length:
RT = PT
x = 5x -28
28 = 4x . . . . . add 28-x
7 = x . . . . . . . .divide by 4
__
QT = ST
5y = 2y +12
3y = 12 . . . . .subtract 2y
y = 4 . . . . . . divide by 3
The values of x and y that make the figure a parallelogram are x=7 and y=4.
