B,C

Step-by-step explanation:

So all you have to do is use the pythagorean theorem to solve this (a²+b²=c²).

Plug in the two shorter sides for a and b and the long side for c. If both sides equal the same thing then it will make a right triangle.

A) 5²+6²=9²

25+36=81

61≠81

B) 0.25+1.44=1.69

C)49+576=625

D) 100+256≠361

E)1+4≠9

(-5,-28)
