Q. Which of the following sets of numbers could represent the three sides of a triangle?{12,16,29}{4,11,17}{12,25,38}{7,10,16}
Triangle Inequality Theorem Application: To determine if a set of numbers can represent the sides of a triangle, we use the triangle inequality theorem. The theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Let's apply this to the first set {12,16,29}. We check if 12 + 16 > 29, 12 + 29 > 16, and 16 + 29 > 12. 12+16=28, which is not greater than 29.
First Set Analysis: Since 12+16 is not greater than 29, the first set of numbers \{12,16,29\} cannot represent the sides of a triangle.
Second Set Analysis: Now let's check the second set 4,11,17. We check if 4 + 11 > 17, 4 + 17 > 11, and 11 + 17 > 4. 4+11=15, which is not greater than 17.
Third Set Analysis: Since 4+11 is not greater than 17, the second set of numbers \{4,11,17\} cannot represent the sides of a triangle.
Fourth Set Analysis: Next, we check the third set 12,25,38. We check if 12 + 25 > 38, 12 + 38 > 25, and 25 + 38 > 12. 12+25=37, which is not greater than 38.
Fourth Set Analysis: Next, we check the third set 12,25,38. We check if 12 + 25 > 38, 12 + 38 > 25, and 25 + 38 > 12. 12+25=37, which is not greater than 38.Since 12+25 is not greater than 38, the third set of numbers 12,25,38 cannot represent the sides of a triangle.
Fourth Set Analysis: Next, we check the third set 12,25,38. We check if 12 + 25 > 38, 12 + 38 > 25, and 25 + 38 > 12. 12+25=37, which is not greater than 38.Since 12+25 is not greater than 38, the third set of numbers 12,25,38 cannot represent the sides of a triangle.Finally, let's check the fourth set 7,10,16. We check if 12 + 25 > 380, 12 + 25 > 381, and 12 + 25 > 382. 12 + 25 > 383, which is greater than 12 + 25 > 384. 12 + 25 > 385, which is greater than 12 + 25 > 386. 12 + 25 > 387, which is greater than 12 + 25 > 388. All conditions are satisfied.
