Question

If ST bisects RSV, m RST =5x-3 and m VST=2x+15 then choose an equation that could be used to solve for x

Answer 1

Answer:

x = 6

Step-by-step explanation:

$\because ST \: bisects\: \angle RSV\\\therefore m\angle RST = m\angle VST\\(by\: \angle \: bisector \: property) \\\therefore 5x - 3 = 2x + 15\\\therefore 5x - 2x = 15 +3\\\purple{\bold {\therefore 3x = 18}} \\\therefore x =\frac{18}{3}\\\huge \orange {\boxed {\therefore x = 6}}$
