Q. Which of the following sets of numbers could not represent the three sides of a triangle?{6,20,24}{6,9,13}{10,25,36}{11,23,33}
Triangle Inequality Theorem: To determine if a set of numbers can represent the sides of a triangle, we use the triangle inequality theorem. The theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. We will apply this theorem to each set of numbers.
Set {6,20,24}: First, we check the set {6,20,24}. According to the triangle inequality theorem, we should have 6 + 20 > 24, 6 + 24 > 20, and 20 + 24 > 6. Let's check these inequalities:6+20=26, which is greater than 24.6+24=30, which is greater than 20.20+24=44, which is greater than {6,20,24}0.All inequalities hold true, so this set could represent the sides of a triangle.
Set {6,9,13}: Next, we check the set {6,9,13}. According to the triangle inequality theorem, we should have 6 + 9 > 13, 6 + 13 > 9, and 9 + 13 > 6. Let's check these inequalities:6+9=15, which is greater than 13.6+13=19, which is greater than 9.9+13=22, which is greater than {6,9,13}0.All inequalities hold true, so this set could represent the sides of a triangle.
Set {10,25,36}: Now, we check the set {10,25,36}. According to the triangle inequality theorem, we should have 10 + 25 > 36, 10 + 36 > 25, and 25 + 36 > 10. Let's check these inequalities:10+25=35, which is not greater than 36. This inequality does not hold true.Therefore, this set cannot represent the sides of a triangle.
Set {11,23,33}: Finally, we check the set {11,23,33}. According to the triangle inequality theorem, we should have 11 + 23 > 33, 11 + 33 > 23, and 23 + 33 > 11. Let's check these inequalities:11+23=34, which is greater than 33.11+33=44, which is greater than 23.23+33=56, which is greater than {11,23,33}0.All inequalities hold true, so this set could represent the sides of a triangle.
