Answer:

RT=5

Step-by-step explanation:

You just have to solve the equations, as you know, RST are collinear and RT equals RS + ST, so we just put that into an equation:

[tex]Rt=RS+ST\\5x-5=x+1+(2x-2)\\5x-5=3x-1\\2x=4\\x=2[/tex]

Now as we know x=2 now we just insert that value into the value of RT:

[tex]RT= 5x-5\\RT= 5(2)-5\\RT=10-5\\RT=5[/tex]

So the answer is RT equals 5 units.
