Similar Angle Triangle
Using similar angle triangle rule SSS, we can find the value of x in this question
[tex]\frac{8}{x} = \frac{12}{18}[/tex]
Let's cross multiply and solve for x
[tex]\frac{8}{x} = \frac{12}{18} \\x = \frac{8*18}{12} \\x = 12cm[/tex]
The value of x in the equation is equal to 12cm.
