Answer:

Nope  B

Step-by-step explanation:

i responded to another of your questions I think, so hopefully this will help!  The pythagorean theorem is a² + b² = c².  This ONLY works with right triangles.  So that means if the numbers work then the triangle is a right triangle.  

Another aspect you need to know is that c is always the longest side.  The other two are interchangeable though, so you just need to remember c is the longest side.  

In this case, that's 8.  8² is 64.  What are 6² + 7²?  85, so that means the numbers do not match up to those of a right triangle.  

For one that does work try it with a triangle with sides  of length 4 ft, 3 ft and 5 ft, just so you have a case where it works.  Also, if you only have two sides you can use algebra to find the third.
