Answer 2

Value of bc will lie in between 1cm and 7cm.

Step-by-step explanation:

In a triangle abc,

ab = 3cm,bc = 4cm

We know that,

In a triangle sum of two sides is always greater than third side.

Hence,

ac+ab > bc

and ac-ab < bc

⇒4+3 > bc

or 7 > bc...........(1)

Also,4 -3 < bc

or 1 < bc.........(2)

Hence from equation (1) and (2),

1cm < bc< 7cm
