Answer 1

Answer:

D. 7

Step-by-step explanation:

LM = 13,

LN = 20,

Since points L, M, and N are collinear, therefore:

$LM + MN = LN$ (segment addition postulate)

$13 + MN = 20$ (substitution)

Subtract 13 from each side of the equation

$13 + MN - 13 = 20 - 13$

$13 - 13 + MN = 7$

$MN = 7$

Possible value of MN is 7.

The answer is D. 7.
