Final answer:
Without further information about RTS or another related equation, it's not possible to find the value of x in the equation RTS = 8x + 18.
Step-by-step explanation:
To find the value of x in the equation RTS = 8x + 18, we need additional information about RTS or a relationship to another equation that lets us solve for x. The question seems to refer to a geometrical context where RTS could be an angle or segment length, but there is no clear geometrical relationship or value for RTS provided to solve for x.
Since the rest of the question contains typos and irrelevant information, we cannot proceed further without clarification. For a valid solution, we must have either the value of RTS or another equation involving x that we can use to set up a system of equations.
