Answer

Yes

Work Step by Step

You have to use the Pythagorean theorem to determine if this is a right triangle. A=1.3, B=8.4, C=8.5: $a^{2}$+$b^{2}$=$c^{2}$ $1.3^{2}$+$8.4^{2}$=$8.5^{2}$ -simplify the exponents- 1.69+70.56=72.25 -simplify like terms- 72.25=72.25 They are equal so yes this is a right triangle.
