Answer
No, it is not a right triangle
Work Step by Step
You have to use the Pythagorean theorem to determine if this is a right triangle.
A=0.7, B=2.3, C=2.5:
$a^{2}$+$b^{2}$=$c^{2}$
$0.7^{2}$+$2.3^{2}$=$2.5^{2}$ -simplify the exponents-
0.49+5.29=6.25 -simplify like terms-
5.78 $\ne$ 6.25
They are not equal so this is not a right triangle.
