Given that pqrs is a square, find x and y.

a. x = 10, y = 10
b. x = 28, y = 47
c. x = 47, y = 28
d. not enough information

Every angle of a square equals 90 degrees.

2x - 4 = 90              3y + 6 = 90
2x = 90 + 4              3y = 90 - 6
2x = 94                    3y = 84
x = 94/2                     y = 84/3
x = 47                        y = 28

so x = 47 and y = 28

Horizontal change or the change of x
