Q. Which of the following sets of numbers could represent the three sides of a triangle?\newline{15,26,41} \{15,26,41\} \newline{5,10,16} \{5,10,16\} \newline{13,27,40} \{13,27,40\} \newline{15,27,40} \{15,27,40\}
  1. 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.
  2. Test First Set: Test the first set of numbers {15,26,41}\{15, 26, 41\} to see if they satisfy the Triangle Inequality Theorem.\newlineCheck if 15+26>4115 + 26 > 41, which is 41>4141 > 41. This is not true, so the set {15,26,41}\{15, 26, 41\} cannot represent the sides of a triangle.
  3. Test Second Set: Test the second set of numbers {5,10,16}\{5, 10, 16\} to see if they satisfy the Triangle Inequality Theorem.\newlineCheck if 5+10>165 + 10 > 16, which is 15>1615 > 16. This is not true, so the set {5,10,16}\{5, 10, 16\} cannot represent the sides of a triangle.
  4. Test Third Set: Test the third set of numbers {13,27,40}\{13, 27, 40\} to see if they satisfy the Triangle Inequality Theorem.\newlineCheck if 13+27>4013 + 27 > 40, which is 40>4040 > 40. This is not true, so the set {13,27,40}\{13, 27, 40\} cannot represent the sides of a triangle.
  5. Test Fourth Set: Test the fourth set of numbers {15,27,40}\{15, 27, 40\} to see if they satisfy the Triangle Inequality Theorem.\newlineCheck if 15+27>4015 + 27 > 40, which is 42>4042 > 40. This is true.\newlineCheck if 15+40>2715 + 40 > 27, which is 55>2755 > 27. This is true.\newlineCheck if 27+40>1527 + 40 > 15, which is 67>1567 > 15. This is true.\newlineSince all conditions of the Triangle Inequality Theorem are satisfied, the set {15,27,40}\{15, 27, 40\} can represent the sides of a triangle.
