Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is 
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.
This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
Answer:
19/40 1.9x0.25=0.475= 19/40
Answer:
I'm leaning mostly towards C Because there is a solution, None of them are real numbers and if they were, S would = 5 Especially positive S
