Question

two side of a triangle are 4 cm and 8 cm then which of the following condition then describe the length of the third side​

Answer 1

Answer:

4 < a < 12 cm

Step-by-step explanation:

In triangles, sum of any two random sides is always greater than the third side, if not, then that triangle can't be formed.

So, here, let other side be 'a'.

 ⇒ 4 cm + 8 cm > a

 ⇒ 12 cm > a

Similarly,

  4 + a > 8

  ⇒ a > 8 - 4

  ⇒ a > 4

Or,       8 + a > 4

           a > 4 - 8

           a > - 4 , neglect this case, as a is already greater than 4.

Hence the other side must be lesser than 12 cm and greater than 4 cm
