Answer:
x = 2.25
Step-by-step explanation:
The above shown trapeziums are similar in shape. So the ratios of their sides should be similar as well. Hence create an equation such as:
[tex]\sf \dfrac{x}5{}=\dfrac{4.5}{10}[/tex]
Then solve it for finding value of x
[tex]\sf x=\dfrac{5(4.5)}{10}[/tex]
Simplify
[tex]\sf x=2.25[/tex]
