Answer:

7

Explanation:

Triangle Proportionality Theorem : If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.


(RP)/(PT) =
(SQ)/(QT) Set up proportions


(6)/(18) =
(x)/(21) Cross multiply

18x = 126 Divide to isolate x

x = 7
