Q. Which of the following sets of numbers could not represent the three sides of a triangle?{11,13,26}{13,19,30}{6,10,15}{13,19,29}
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 {11,13,26} to see if they satisfy the Triangle Inequality Theorem.Calculate if 11 + 13 > 26.11+13=24, which is not greater than 26.
First Set Not Satisfactory: Since 24 is not greater than 26, the set \{11, 13, 26\} does not satisfy the Triangle Inequality Theorem and therefore cannot represent the sides of a triangle.
Check Second Set: Check the second set of numbers {13,19,30} to see if they satisfy the Triangle Inequality Theorem.Calculate if 13 + 19 > 30.13+19=32, which is greater than 30.
Second Set Satisfactory: Check the other combinations for the second set to ensure all conditions of the Triangle Inequality Theorem are met.Calculate if 13 + 30 > 19 and 19 + 30 > 13.13+30=43, which is greater than 19.19+30=49, which is greater than 13.
Check Third Set: Since all conditions are met for the second set, {13,19,30} could represent the sides of a triangle.
Third Set Satisfactory: Check the third set of numbers {6,10,15} to see if they satisfy the Triangle Inequality Theorem.Calculate if 6 + 10 > 15.6+10=16, which is greater than 15.
Check Fourth Set: Check the other combinations for the third set to ensure all conditions of the Triangle Inequality Theorem are met.Calculate if 6 + 15 > 10 and 10 + 15 > 6.6+15=21, which is greater than 10.10+15=25, which is greater than 6.
Fourth Set Satisfactory: Since all conditions are met for the third set, {6,10,15} could represent the sides of a triangle.
Fourth Set Satisfactory: Since all conditions are met for the third set, {6,10,15} could represent the sides of a triangle.Check the fourth set of numbers {13,19,29} to see if they satisfy the Triangle Inequality Theorem.Calculate if 13 + 19 > 29.13+19=32, which is greater than 29.
