Answer:

No solution

Step-by-step explanation:

If you were to do elimination, both the x and the y would cancel out and get 0=1, which is not true. And if you were to do it as substitution, then it would still get an answer that doesn't make sense.

Rectangle RSUT has diagonals that meet at point x.

Stels [109]

Answer:

x=12.5

y=10

Step-by-step explanation:

Properties of rectangle:

Opposite sides are congruent
All angles are right angles
Diagonals bisect each other
Diagonals are of equal length

so from the properties we came to know that diagonals bisects each other and diagonals are of equal length

Given Rectangle RSUT has diagonals that meet at point X.

⇒ $RX=SX=UX=TX=\frac{1}{2}RU=\frac{1}{2}ST$

⇒ $RX=\frac{1}{2}ST$

⇒ $4x=\frac{1}{2}(100)$

⇒ $x=12.5$

Also $XU=RX$

⇒ $(4)(12.5)=5y$

⇒ $5y=50$

⇒ $y=10$
