Question

in ∆ABC,AB=4 and BC=7 Then ________. holds good​

Answer 1

Answer:

CD = 12

Step-by-step explanation:

Because in a triangle sum of two sides should be greater than the third.

Here, AB+CD = 7+4 = 11

And CD= 12  so 12>11

Answer 2

Answer:

AC >11, will always hold good in  ∆ABC

Step-by-step explanation:

Given,

in ∆ABC,AB=4 and BC=7

Required to find,

an expression that always holds good in the case of the ∆AB

Recall the concept,

The sum of the lengths of any two sides of a triangle will always be greater than the third side.

Solution:

Given,

∆ABC,AB=4 and BC=7

Since the sum of the lengths of any two sides of a triangle will always be greater than the third side.

We have

AC > AB+BC

AC > 4+7

AC >11

AC >11, will always holds good in  ∆ABC
