Quadrilateral abcd is a parallelogram if its diagonals bisect each other. prove that quadrilateral abcd is a parallelogram by finding the value of x. a) x = 2 b) x = 3 c) x =- 9|2 d) x = -3|4 information that goes with the picture: ao = 5x + 2 bo = x − 1 co = 3x − 7 do = 3x + 8

Because this is a parallelogram, we know that the diagonals bisect. This means that AO = DO, and CO = BO

It doesn't matter which two segments we use, but I'm going to use CO = BO for this one.

3x - 7 = x - 1

2x = 6

x = 3

Option B. is the answer.

c. 16 units
