Answer 2

Answer:

length of third side should be greater than 5 and less than 13

Step-by-step explanation:

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

here the lengths of two sides are 4 and 9 respectively.

4+9=13, implies that the lenght of the third side should be less than 13.

now let the unknown length be X. then following the above property,

X+4>9 and

X+9>4( we can ignore this inequality since 9 is already greater than 4)

now,X+4>9 implies X>9-4, implies X>5.

there the length of third side should be greater than 5 and less than 13
