\( \begin{array}{ll}\text { a) } \frac{15}{20}=\frac{21}{x} & \text { b) } \frac{6}{24}=\frac{x}{21} \\ \text { c) } \frac{x}{24}=\frac{40}{64} & \text { d) } \frac{28}{x}=\frac{35}{55} \\ \text { e) } \frac{x}{72}=\frac{53}{212} & \text { f) } \frac{17}{x}=\frac{68}{372} \\ \text { g) } \frac{14}{35}=\frac{284}{x} & \text { h) } \frac{24}{x}=\frac{x}{54} \\ \text { i) } \frac{9}{x}=\frac{x}{25} & \text { j) } \frac{x}{24}=\frac{54}{x}\end{array} \)

Use substitution to determine whether the given \( x \)-value is a solution of the equation. \[ \cos x=\sin 3 x, x=\frac{\pi}{6} \]
