Answer:
x = 5.4
Step-by-step explanation:
since the figures are scaled factors of each other then they are similar.
the ratios of corresponding sides are therefore in proportion, that is
[tex]\frac{x}{7.2}[/tex] = [tex]\frac{3}{4}[/tex] ( cross- multiply )
4x = 21.6 ( divide both sides by 4 )
x = 5.4
