wariber [46]

Answer:

  A. 8

Step-by-step explanation:

The length of the remaining side will be between the sum and difference of the given sides:

  5 + 13 = 18 . . . . upper limit of 3rd side length

  13 - 5 = 8 . . . . . lower limit of 3rd side length

The only answer choice in this range is 8.

_____

<em>Comment on question and answers</em>

Please note that this would not be an allowed answer for some triangle inequality questions. Some authors insist that the sum of the two shortest sides be <em>greater than</em> the longest side, so the triangle has non-zero area. Other authors allow the sum to be <em>greater than </em><u><em>or equal to</em></u> the longest side. The only viable answer choice here is one that makes use of the "or equal to" condition. The 5-8-13 triangle will look like a line segment of length 13. It will have no area.
