Question

Find values of x and y for which ABCD must be a parallelogram. The diagram is not drawn to scale.

Answer 1

choices are;

A. x = 10; y = 38
B. x = 10; y = 21
C. x = 10; y = 7
D. x = 7; y = 10

Answer 2

with any parallelogram, the diagonals bisect each other

Answer 3

so basically the diagonals cut each other in half

Answer 4

so this means

4y - 7 = y + 14

and

4x - 2 = x + 28
