3. IF ON = 5x - 7, LM = 4x +4, NM = x - 7, and OL = 3y – 4, find the values of x and y for which LMNO must
be a parallelogram. The diagram is not to scale.
N CH-7=5X

Answer :

Answer:

x = 11 and [tex]y = \frac{8}{3}[/tex]

Step-by-step explanation:

If LMNO is a parallelogram then it's opposite sides will be equal.

So, LM = ON

⇒ 4x + 4 = 5x - 7

⇒ x = 11

Now, MN = OL  

⇒ x - 7 = 3y - 4

⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}

⇒ [tex]y = \frac{8}{3}[/tex] (Answer)
