try 7

Step-by-step explanation:

Answer:

this is tricky b/c they are making the two triangles of different scales but of the same angles.... soooo  one is just a bigger copy of the other....

Step-by-step explanation:

Since this is a relation of the two side of each.. we can say the following...

[tex]\frac{6}{9}[/tex] = [tex]\frac{4}{x}[/tex]     where X = side  LA    soooo       solve for X  

 x *  [tex]\frac{6}{9}[/tex] = 4   (move the X , to the other side of the '=' sign

x = 4 * [tex]\frac{9}{6}[/tex]   ( yes.. we want to invert the fraction to move it to the other side )

x = [tex]\frac{36}{6}[/tex]

x = 6

so side LA is 6    :)
