Answer:
x = 30
Step-by-step explanation:
well from the theorem we have
[tex]\frac{15}{3}=\frac{x}{6}[/tex]
yes i know you could say that the right way is
[tex]\frac{3}{15}=\frac{6}{x}[/tex]
well if you notice they are the same only that in my way the x is in the numerator which means it will be far easier to know it's value :)
so
[tex]\frac{15}{3}=\frac{x}{6}\\\\5=\frac{x}{6}\\\\6[5]=6[\frac{x}{6}]\\\\30=x[/tex]
