#### 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=1.2, B=6, C=6.1: $a^{2}$+$b^{2}$=$c^{2}$ $1.2^{2}$+$6^{2}$=$6.1^{2}$ -simplify the exponents- 1.44+36=37.21 -simplify like terms- 37.44=37.21 They are not equal so this is not a right triangle.
