Answer:

x = 6

Step-by-step explanation:

[tex] \because ST \: bisects\: \angle RSV\\

\therefore m\angle RST = m\angle VST\\

(by\: \angle \: bisector \: property) \\

\therefore 5x - 3 = 2x + 15\\

\therefore 5x - 2x = 15 +3\\

\purple{\bold {\therefore 3x = 18}} \\

\therefore x =\frac{18}{3}\\

\huge \orange {\boxed {\therefore x = 6}} [/tex]
