To start you just need to use Pythagorean Theorem.
a^2+b^2=c^2

@Ambbiiee what answer did you come up with for 5?

anonymous · Answer

The answer to number 5 is B

mathlegend · Answer

@BronxWarrior lets not just give answers. @Ambbiiee has to do the work. It would be best if Ambbiiee actually showed us the process.

anonymous · Answer

i picked B but my teacher said it was wrong @MathLegend

mathlegend · Answer

Remember it says which do NOT form a right triangle. If $$a ^{2} + b ^{2} = c ^{2}$$
Then it is a Right Triangle. You are looking for one where the operations do not add up.

wait no

mathlegend · Answer
