What is the length, in units, of JK?

6

4

2 square root 8

8 square root 2

Answer 1

set up a ratio i think

Answer 2

is KM=8

Answer 3

ML is 8 I dont think it is to scale

Answer 4

option D: 8 sq rt 2

Answer 5

look at the triangle, the Big triangle.. Cos J = JK/16

and small triangle, JKM = Cos J = 8 / JK

equate both ; JK/16 = 8 / JK

Jk2 = 8 * 16 = 8 * 8 * 2
Therefore, JK = 8\[\sqrt{2}\]...

Answer 6

8*sqrt(2)
cuzz km is altitude

Answer 7

angles in asemicicle is a rt angle then JM=ML=KM=8 (IF ML =8 )
plz check the answer
