Answer:

AB = 12    BC = 5   AC = 13

Step-by-step explanation:

opposite sides of a rectangle are congruent, therefore AB = DC = 12

and BC = AD = 5.

Now, AC is found by using the Pythagorean theorem.  

So, [tex]AC^{2}[/tex] = [tex]AB^{2}[/tex] + [tex]BC^{2}[/tex]

            = [tex]12^{2}+5^{2}[/tex]

            = 144 + 25 = 169

AC = [tex]\sqrt{169}[/tex] = 13

Answer:

12,5, and 13
