2)5.5cm,13cm,7.5cm.
plz it's urgent please step by step .... ​

Answer 1

Step-by-step explanation:

1)6,7,8

6+7=13(more than third side i.e 8)

7+8=15(more than third side i.e 6)

6+8=14(more than third side i.e 7)

So,here the triangle can be formed.

2) 5.5,13,7.5

5.5+13=18.5(more than third side i.e 7.5)

7.5+5.5=13(equal to the the third side i.e 13)

7.5+13=20.5(more than third side i.e 5.5)

So,here the triangle can be formed.
