Question

A triangle has side lengths measuring 20 cm, 5 cm, and n cm. Which describes the possible values of n? O 5​

Answer 1

15 < n < 25

Explanation:

The length of the third side should be,

• Greater than the difference between the length of the two sides and
• Less than the sum of the two sides.

Difference of two sides = 20 - 5 = 15

Sum of two sides = 20 + 5 = 25

'n' should be greater than 15 and less than 25.
