jhonyy9:

the way how you got this result please ?

Gucchi:

okay so i used the triangle inequality theorem which states that any side of the triangle must be shorter than the sum of the other sides. the sum of given sides is: 8 + 5 = 13 units The remaining side must be less than 13 units, which is a- 12 units, and all the other options are greater than 13 units
