BRAINLIEST GIVER HERE..PLEASE HELP!

Mathematics
1 answer:
galben [10]3 years ago
4 0

Answer:

12.8

Step-by-step explanation:

Theorem: The median of a trapezoid is parallel to each base and the length of the median equals one-half the sum of the lengths of the two bases.

OB = (1/2)(AT + KN)

9.12 = (1/2)(5.44+ KN)

Multiply both sides by 2

18.24 = 5.44 + KN

Subtract 5.44 from both sides

12.8 = KN
