Answer:
10
Step-by-step explanation:
B
Since the triangles are similar then the ratio of corresponding sides are equal, that is
[tex]\frac{EF}{JK}[/tex] = [tex]\frac{EG}{JL}[/tex] , substitute values
[tex]\frac{24}{16}[/tex] = [tex]\frac{3x-9}{14}[/tex] ( cross- multiply )
16(3x - 9) = 336 ( divide both sides by 16 )
3x - 9 = 21 ( add 9 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10 → B
