Answer
c=6.5
Work Step by Step
The legs are 2.5 and 6. You have to find the hypotenuse using $a^{2}$+$b^{2}$=$c^{2}$. Plug in the legs for A and B:
$a^{2}$+$b^{2}$=$c^{2}$
$2.5^{2}$+$6^{2}$=$c^{2}$ -simplify exponents-
42.25=$c^{2}$ -find the square root of 42.25 to solve for c-
$6.5=c$
The hypotenuse is 6.5.
