Answer
C=12.5
Work Step by Step
The legs are 3.5 and 12. You have to find the hypotenuse using $a^{2}$+$b^{2}$=$c^{2}$. Plug in the legs for A and B:
$a^{2}$+$b^{2}$=$c^{2}$
$3.5^{2}$+$12^{2}$=$c^{2}$ -simplify exponents-
156.25=$c^{2}$ -find the square root of 156.25 to solve for c-
12.5=c
Thus, the hypotenuse is 12.5.
