Answer:
4
Step-by-step explanation:
with a 30-60-90 triangle the hypotenuse is 2x while the smaller 30 side is x. This means that LJ is 4[tex]\sqrt{2}[/tex]. Then for a 45-45-90 the hypotenuse is [tex]x\sqrt{2}[/tex] compared to a leg being X. So you remove the [tex]\sqrt{2}[/tex] leaving you with 4
