Answer:
12
Step-by-step explanation:
Diagonals of a rhombus bisect each other at right angles, so in triangle JNK, we have JK=20 and JN=16.
Using the Pythagorean theorem, it follows that KN = 12.
Answer:
s = 2
Step-by-step explanation:
6s - 4 = 8
Additive inverse of (-4) is 4. So, add 4 to both the sides
6s - 4 + 4 = 8 + 4
6s = 12
Now divide both the sides by 6.

s = 2
