Q. Which of the following sets of numbers could represent the three sides of a triangle?{10,13,22}{14,26,42}{6,14,22}{15,18,34}
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 Set {10,13,22}: Apply the Triangle Inequality Theorem to the first set {10,13,22}.Check if 10 + 13 > 22, 10 + 22 > 13, and 13 + 22 > 10.Calculation: 10+13=23, 10+22=32, 13+22=35.23 > 22 (True), 32 > 13 (True), but {10,13,22}0 (True).However, the first condition 10 + 13 > 22 is not satisfied, so this set cannot represent the sides of a triangle.
Apply Theorem to Set {14,26,42}: Apply the Triangle Inequality Theorem to the second set {14,26,42}.Check if 14 + 26 > 42, 14 + 42 > 26, and 26 + 42 > 14.Calculation: 14+26=40, 14+42=56, 26+42=68.40 > 42 (False), 56 > 26 (True), and {14,26,42}0 (True).The first condition 14 + 26 > 42 is not satisfied, so this set cannot represent the sides of a triangle.
Apply Theorem to Set {6,14,22}: Apply the Triangle Inequality Theorem to the third set {6,14,22}.Check if 6 + 14 > 22, 6 + 22 > 14, and 14 + 22 > 6.Calculation: 6+14=20, 6+22=28, 14+22=36.20 > 22 (False), 28 > 14 (True), and {6,14,22}0 (True).The first condition 6 + 14 > 22 is not satisfied, so this set cannot represent the sides of a triangle.
Apply Theorem to Set {15,18,34}: Apply the Triangle Inequality Theorem to the fourth set {15,18,34}.Check if 15 + 18 > 34, 15 + 34 > 18, and 18 + 34 > 15.Calculation: 15+18=33, 15+34=49, 18+34=52.33 > 34 (False), 49 > 18 (True), and {15,18,34}0 (True).The first condition 15 + 18 > 34 is not satisfied, so this set cannot represent the sides of a triangle.
