Answer : A, C AND D

using the Triangle Inequality Theorem

It state that the sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Taking, 19 , 11, and 17

Let the first length = a

second length = b

Third length = c

According to the rule

a + b > c

19 + 11 > 17

30 > 17 ----------- This could represent the side lengths of a triangle

For 23, 28, 52

a = 23, b = 28, and c = 52

a + b > c

23 + 28 < 52

51 < 52 ..................... This can not represent the side lengths of a triangle

For 34, 9 , and 25

let a = 34, b = 9, and c = 25

a + b > c

34 + 9 > 25

43 > 25 ---------------------- This could represent the side lengths of a triangle

For 13, 22, 14

a = 13 , b = 22 and c = 14

a + b > c

13 + 22 > 14

35 > 14 ----------------- This could represent the side lengths of a triangle
