The lengths of the sides of a triangle are 12, 13, and n. which of the following must be true? n≥1 n< 13 1

Step-by-step explanation:

Choices for this question are

( A ) n greater than or equal to 1

( B ) n < 13

( C ) 1 < n < 13

( D ) 1 < n < 25

The triangular inequality theorem states that the sum of two sides of a triangle must be greater than the third side. That means

Also, that third side most be greater than 1, other wise, the side wouldn't exist.

Therefore, according to the triangular inequality theorem, the best answer is D. 1 < n < 25
