Answer:

LM=12

V =90

Step-by-step explanation:

4.  If it is a parallelogram, the two sides have to be equal.

2x-6 = x+3

Subtract x from each side

2x-x -6 = x+3-x

x-6 =3

Add 6 to each side

x-6+6 = 3+6

x=9


LM =2x-6

    = 2*9 -6

   = 18-6

   = 12

5.  

<U + < T = 180   Adjacent corners in a parallelogram are supplementary

11x+2 + 12x-6 = 180

Combine like terms

23x -4 = 180

Add 4 to each side

23x-4+4 = 180+4

23x = 184

Divide by 23

23x/23 = 184/23

x=8

<V = <T  Opposite corners in a parallelogram are equal.

<V = 12x-6

<V = 12(8) -6

<V = 96-6

<v =90
