#### Answer

$a = \sqrt{34}$
$b = \sqrt{29}$
$c = \sqrt{13}$

#### Work Step by Step

$A = (2,5)$
$B = (-1,3)$
$C = (4,0)$
We can find the length of side $a$:
$a = \sqrt{(4-(-1))^2+(0-3)^2}$
$a = \sqrt{34}$
We can find the length of side $b$:
$b = \sqrt{(4-2)^2+(0-5)^2}$
$b = \sqrt{29}$
We can find the length of side $c$:
$c = \sqrt{(2-(-1))^2+(5-3)^2}$
$c = \sqrt{13}$
