Answer:
The length of side AC is 4 units
Step-by-step explanation:
Find the diagram in the attachment below.
In order to determine the length of side AC, we will use the formula for calculating the distance between two points as shown;
[tex]D = \sqrt{(x_2-x_1)^{2} + (y_2-y_1)^{2}}[/tex]
For side AC with A (-2, 1) and C (-2, -3)
x1 = -2, y1 = 1, x2 = -2, y2 = -3
[tex]AC = D = \sqrt{(-2-(-2))^{2} + (-3-1)^{2}}\\AC = \sqrt{0^{2} + (-4)^{2}}\\AC = \sqrt{16} \\AC = 4[/tex]
The length of side AC is 4 units
