Answer:
C. 4
Step-by-step explanation:
We can use power of a point to solve this problem. From this, we can set up the equation:
MN^2 = LM x MK
MK would be the sum of LM and KL because of segment addition postulate. Therefore, we can say MK = 2 + 6 = 8
Now, we can substitute the values we have in the equation above:
MN^2 = 2 x 8
MN^2 = 16
MN = 4
