Answer 1

Which of the following can be the length of BC required to construct the triangle ABC such that

AC = 7.4 cm and AB = 5 cm?

Answer 2

BC will be greater than 2.4

Given:

triangle ABC,

AC = 7.4 cm

and AB = 5 cm

To find:

Which of the following can be the length of BC required to construct the triangle ABC such that

AC = 7.4 cm and AB = 5 cm?

Solution:

In a Triangle,

• The sum of the length of any two sides of a triangle is greater than the length of the third side.

• by using the above property, we get,

                   side 1(AB) + side 2(BC) > side 3(AC)

( by substituting above values in given equation)

    ==>  5 + BC > 7.4

    ==>   BC > 7.4 - 5

    ==>   BC> 2.4

BC will be greater than 2.4
