Question

Use parallelogram ADCB to solve for x and y.

Answer 1

Answer:

x = 5

y = 17

Step-by-step explanation:

diagonals of a parallelogram bisect each other so:

11 = x+6

x = 5

10 = y-7

17 = y

Answer 2

Answer:

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so you get two equations.

• y - 7 = 10
• x + 6 = 11

y - 7 = 10                  Add 7 to both sides

y = 10 +  7

y = 17

x + 6 = 11                 Subtract 6 from both sides.

x + 6 - 6 = 11 - 6

x = 5
