Answer:

\Large \boxed{\sf x=9}

Step-by-step explanation:

A transversal that is parallel to a side in a triangle defines a new smaller triangle that is similar to the bigger triangle.

\displaystyle \frac{9+72}{9} =\frac{3x-20+56}{3x-20}

Solve for <em>x</em>

(9+72)\times(3x-20)=(3x-20+56)\times(9)

243x-1620=27x+324

216x=1944

x=9
