Answer 1

Answer:

13/3

Step-by-step explanation:

ON=LM

8X-8 = 7X+4

let's find "x"

8x - 7x = 4 + 8

x = 12

now NM = OL

X-5 = 3Y-6

then

(12) - 5 = 3y - 6

7 = 3y - 6

3y = 7+6

y = 13/3

Answer 2

Six important properties
of parallelograms to know:

Opposite sides are congruent (ON=LM)

Opposite angels are congruent (L= N)

Consecutive angles are supplementary (O+ L= 180°).

If one angle is right, then all angles are right.

The diagonals of a parallelogram bisect each other.

Each diagonal of a parallelogram separates it into two congruent triangles.
