Answer 1

Answer:

to check whether triangle is possible or not...

then the sum of 2 side should be more than the 3rd one...

1. $3 + 4 < 5 \\ 4 + 5 < 3 \\ 3 + 5 < 4$so tringle is possible in this case
2. $3 + 5 < 5 \\ 3 + 5 < 5 \\ 5 + 5 < 3$triangle is possible in this case also
3. $5.5 + 2.2 < 3.1 \\ 5.5 + 3.1 < 2.2 \\ 3.1 + 2.2 \: not \: greater \: 5.5$triangle is not possible in this case
4. $9.3 + 5.2 < 7.4 \\ 9.3 + 7.4 < 5.2 \\ 7.4 + 5.2 < 9.3$triangle is possible.☺☺
