Answer:

opposite sides of a parallelogram are equal

2x+15=x+15

2x-x=15-15

x=0

Answer:

x = 0

Step-by-step explanation:

The opposite sides of a parallelogram are congruent, that is

ST = RU , substitute values

2x + 15 = x + 15 ( subtract x from both sides )

x + 15 = 15 ( subtract 15 from both sides )

x = 0
