A and C
Step-by-step explanation: To see if it can be the side lengths of a right triangle we have to use the Pythagoras Theorem which is![a^2 +b^2 = c^2\\](/tpl/images/1381/6262/3dac0.png)
C is always the largest length. Now we can sub the numbers in
The squares and the square roots cancel each other out so we end up with
25+6=31
this is true so those are possible sides for a right triangle
Now for b:
Again the squares and square roots cancel each other out
5+5=2500
This isn't true so it isn't the possible sides for a right triangle
Finally option C:
81+144=225
225=225
This is true so it can be the side lengths that form a right triangle
