#### Answer

No,this 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=8, B=40, C=41):
$a^{2}$+$b^{2}$=$c^{2}$
$8^{2}$+$40^{2}$=$41^{2}$ -simplify the exponents-
64+1600=1681-simplify like terms-
1664=1681
They are not equal so this is not a right triangle. It is an obtuse triangle.
