Q. Which of the following sets of numbers could represent the three sides of a triangle?{5,17,23}{6,20,25}{5,17,24}{10,13,25}
Recall Triangle Inequality Theorem: Recall the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
Apply Theorem to First Set: Apply the Triangle Inequality Theorem to the first set 5,17,23. Check if 5 + 17 > 23, 5 + 23 > 17, and 17 + 23 > 5.
Check First Set Calculations: Perform the calculations for the first set: 5+17=22, which is not greater than 23. Therefore, the first set \{$\(5\),\(17\),\(23\)\} cannot represent the sides of a triangle.
Apply Theorem to Second Set: Apply the Triangle Inequality Theorem to the second set \({6,20,25}\). Check if \(6 + 20 > 25\), \(6 + 25 > 20\), and \(20 + 25 > 6\).
Check Second Set Calculations: Perform the calculations for the second set: \(6 + 20 = 26\), which is greater than \(25\). Now check the other two conditions.
Apply Theorem to Third Set: For the second set, check if \(6 + 25 > 20\), which is \(31 > 20\), and \(20 + 25 > 6\), which is \(45 > 6\). All conditions are satisfied, so the second set \{\(6,20,25\)\} could represent the sides of a triangle.
Check Third Set Calculations: Apply the Triangle Inequality Theorem to the third set \({5,17,24}\). Check if \(5 + 17 > 24\), \(5 + 24 > 17\), and \(17 + 24 > 5\).
Apply Theorem to Fourth Set: Perform the calculations for the third set: \(5 + 17 = 22\), which is not greater than \(24\). Therefore, the third set \{\(5,17,24\)\} cannot represent the sides of a triangle.
Check Fourth Set Calculations: Apply the Triangle Inequality Theorem to the fourth set \(\{10,13,25\}\). Check if \(10 + 13 > 25\), \(10 + 25 > 13\), and \(13 + 25 > 10\).
Check Fourth Set Calculations: Apply the Triangle Inequality Theorem to the fourth set \(\{10,13,25\}\). Check if \(10 + 13 > 25\), \(10 + 25 > 13\), and \(13 + 25 > 10\). Perform the calculations for the fourth set: \(10 + 13 = 23\), which is not greater than \(25\). Therefore, the fourth set \(\{10,13,25\}\) cannot represent the sides of a triangle.
