Atriangle has side lengths measuring 20 cm, 5 cm, and n cm. which describes the possible values of n?
5 5 15 15

d)  The possible value of n can be expressed as 15 < n < 25.

Step-by-step explanation:

Here, the given sides of the triangle are:

First Side  = 20 cm

Second Side = 5 cm

Third side  = n cm

Now ,as we know " SUM OF ANY TWO SIDES OF A TRIANGLE IS ALWAYS GREATER THAN THE THIRD SIDE"

⇒  Length of ( First + Second ) side > Third Side

or,( 20 cm + 5 cm ) > n cm

or, n < 25 cm

Now, from all given options,

15 < n < 25 is the MOST APPROPRIATE.

Hence, the possible value of n can be expressed as 15 < n < 25.

i used to know how to do this in 7th but i forget easily
