Answer:
x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The figures are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{8}{3}[/tex] = [tex]\frac{4}{x}[/tex] ( cross- multiply )
8x = 12 ( divide both sides by 8 )
x = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex] = 1.5
