Answer
A=0.7
Work Step by Step
The hypotenuse is 2.5 and one of the legs is 2.4. Find the other leg using $a^{2}$+$b^{2}$=$c^{2}$. Plug in the leg for B and the hypotenuse for C:
$a^{2}$+$b^{2}$=$c^{2}$
$a^{2}$+$2.4^{2}$=$2.5^{2}$ -simplify the exponents-
$a^{2}$ + 5.76=6.25 -subtract 5.76 from both sides-
$a^{2}$=0.49 -find the square root of 0.49 in order to solve for a-
$a=0.7$
The other leg is 0.7.
