Which of the following sets of numbers could be the sides of a triangle? 6, 8, and 15 9, 13, and 17 2, 3, and 6 10, 10, and 20

6, 8 and 15 and2, 3 and 6and10, 10 and 20can not be sides of a ∆.therefore, the one that's left is the answer.

To be the sides of the triangle the sum of any two sides should be always more than a 3d side.1) 6+8 and 1514< 15, so it is no triangle possible.3) 2+3 and 65< 6, so it is no triangle possible.4) 10+10 and 2020=20, so it is no triangle possible.2) 9+13> 17, 22> 17 true13+17> 9, 30> 9 true  17+9> 13, 26> 13 trueso, with sides  9, 13, and 17,  triangle is possible.
