use this formula :
JK^2 = JM * JL
so,
JK^2 = 8 * 16
solve for JK (then simplify it)

This is a right triangle, so Pythagoras could help.  Label EVERYTHING you can.  What do you notice about the two smaller triangles?

.... golden ratio comes to mind as well :)  but my mind is not what it used to be ...

raden · Answer

yeah, i used the similarity of triangles JKM and JKL :)
JK/JL = JM/JK, therefore
JK^2 =  JM * JL
