Answer 1

Answer:d

Step-by-step explanation:i just did the test

Answer 2

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

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.
