Find x and y so the quadrilateral is a parallelogram.

We conclude that:

Step-by-step explanation:

Given

We know that the diagonals of a parallelogram bisect each other.

so

Given

so substituting RT = x, and TP = 5x-28

divide both sides by 4

Therefore, the value of x:

Similarly,

Given

so substituting QT = 5y, and TS = 2y+12

divide both sides by 3

Therefore, the value of y:

y = 4

Therefore, we conclude that:

i found two solutions,   n = 2 • ± √3 = ± 3.4641
