Answer:
[tex]|JK|=3\sqrt{3}[/tex]
Step-by-step explanation:
The diagram of the triangle is drawn and attached,
From trigonometric ratios,
[tex]cos \theta =\frac{Adjacent}{Hypotenuse} \\cos60^\circ =\frac{|JK|}{|JL|}\\ 0.5=\frac{|JK|}{6\sqrt{3} }\\$Cross multiply$\\|JK|=0.5*6\sqrt{3}\\|JK|=3\sqrt{3}[/tex]
