Question

A triangular piece of glass has sides that measure 39 in., 81 in., and 89 in. Is the piece of glass in the shape of a right triangle?

Answer 1

Step-by-step explanation:

C²=a²+b²

a²+b²=c²

81²+89²=39²

6561+7921=1521

14482=1521

the sides are not equal

not a right triangle

so the given sides are not the sides of a right triangle
