MatroZZZ [7]

Answer: 11

Step-by-step explanation:

Given

The side of the triangle are 24\ \text{and }35

Also, the sum of the two sides of the triangle is always greater than the third

\therefore x

Similarly,

Also,

\Rightarrow x+24>35\\\Rightarrow x>11\quad \ldots(ii)

From (i) and (ii) we get

\Rightarrow 11
