Q. Which of the following sets of numbers could represent the three sides of a triangle?{13,27,41}{8,21,29}{14,18,34}{4,16,17}
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.
Check First Set: Check the first set of numbers {13,27,41} to see if they satisfy the Triangle Inequality Theorem.We need to check if:13 + 27 > 41,13 + 41 > 27, and27 + 41 > 13.
Perform First Set Calculations: Perform the calculations for the first set.13+27=40, which is not greater than 41.This means that the first set of numbers cannot represent the sides of a triangle.
Check Second Set: Check the second set of numbers {8,21,29} to see if they satisfy the Triangle Inequality Theorem.We need to check if:8 + 21 > 29,8 + 29 > 21, and21 + 29 > 8.
Perform Second Set Calculations: Perform the calculations for the second set.8+21=29, which is not greater than 29.This means that the second set of numbers cannot represent the sides of a triangle.
Check Third Set: Check the third set of numbers {14,18,34} to see if they satisfy the Triangle Inequality Theorem.We need to check if:14 + 18 > 34,14 + 34 > 18, and18 + 34 > 14.
Perform Third Set Calculations: Perform the calculations for the third set. 14+18=32, which is not greater than 34. This means that the third set of numbers cannot represent the sides of a triangle.
Check Fourth Set: Check the fourth set of numbers {4,16,17} to see if they satisfy the Triangle Inequality Theorem.We need to check if:4 + 16 > 17,4 + 17 > 16, and16 + 17 > 4.
Perform Fourth Set Calculations: Perform the calculations for the fourth set.4+16=20, which is greater than 17.4+17=21, which is greater than 16.16+17=33, which is greater than 4.All conditions are satisfied, so the fourth set of numbers can represent the sides of a triangle.
