Question

current skill $ ments could represent the side lengths of 31 yd, 64 yd, 70 yd 14 yd, 67 yd, 77 yd 380 yd, 399 yd, 551 yd 49 yd, 77 yd, 83 yd skill code: 79014

Explanation:

Step1: Recall triangle - inequality theorem

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Step2: Check option 1

For side - lengths 31 yd, 64 yd, 70 yd:
$31 + 64=95>70$, $31 + 70 = 101>64$, $64+70 = 134>31$.

Step3: Check option 2

For side - lengths 14 yd, 67 yd, 77 yd:
$14+67 = 81>77$, $14 + 77=91>67$, $67 + 77 = 144>14$.

Step4: Check option 3

For side - lengths 380 yd, 399 yd, 551 yd:
$380+399 = 779>551$, $380 + 551=931>399$, $399 + 551 = 950>380$.

Step5: Check option 4

For side - lengths 49 yd, 77 yd, 83 yd:
$49+77 = 126>83$, $49 + 83=132>77$, $77 + 83 = 160>49$.

Since all the given sets of side - lengths satisfy the triangle - inequality theorem, all of them could represent the side lengths of a triangle.

Answer:

All of the above (assuming the options are the four sets of side - lengths given: 31 yd, 64 yd, 70 yd; 14 yd, 67 yd, 77 yd; 380 yd, 399 yd, 551 yd; 49 yd, 77 yd, 83 yd)
