Multiple Choice Answers
left curly bracket, 6, comma, 8, comma, 10, right curly bracket{6,8,10}
left curly bracket, 25, comma, 60, comma, 65, right curly bracket{25,60,65}
left curly bracket, 30, comma, 40, comma, 50, right curly bracket{30,40,50}
left curly bracket, 13, comma, 84, comma, 86, right curly bracket{13,84,86}

The set of numbers {13, 84, 86} could not represent the three sides of a right triangle because the Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. In this case, 86^2 is greater than 13^2 + 84^2.
