Question

the lenghts of two sides of a triangle vare 5 cm and 8cm . between what two measures should vthe length of third side fall?​

Answer 1

Answer:

It is known that the sum of the two sides of a triangle is greater than the third side, so,

thirdside<5+8

thirdside<12

And,

thirdside>8−5

thirdside>3

Therefore, 3<thirdside<12.

Hence, the third side of the triangle falls between (3,12).
